Selling power supply unit from the radio "Aelita 102". Prophylaxis was made, K50-6 was replaced in the reference voltage source, thermal paste was placed between the regulating transistor and the radiator. The axial electrolytic capacitor in the rectifier did not change, because with the capacity and esr everything is in order. A stabilized voltage of 14 volts was tested with a load consuming more than 10 watts (750 milliamperes), while the PSU output was 13.98 volts. Ripple amplitude 25 millivolts at the same load.

There are scratches on the case of the power supply unit, and there is no power plug. Sending from Saransk by Russian Post or TC "Business lines", "PEK". The lot is exhibited on other resources.

The price is 600 rubles, or I will exchange it for a measuring record “IZM 33s 0201-02” or “IZM 0281-2”.

The very first thing is washing, the rest is later.
Eh. at one time I repaired them under warranty!

GOGA Riga - Yeah, he showed up.
I gave these three years ago 4 pieces. Right now, there are already two - one for the details + Aelita. the same pogrom.
A very good receiver, a pleasant sound, an ugly tape recorder - you can kill an LPM.

I never made the TR generator.

In those years, and the rig 110 was produced since 1980, these were very popular machines.
The import cost an unimaginable tyshhi, and these 380 rubles. Lifting price.
Nobody really dragged them, except to the beach.
They were especially convenient for a summer residence or a garden plot.

Notes of the Soviet consumer.
I used to have Riga-110, Aelita -111, VEF-260 sigma. (Under seals). Riga and VEF with quality marks.
Riga 110 in a black case - a tape recorder of poor quality, in the VHF receiver it does not hold the frequency due to varicaps. (The same problems with the VHF unit were in the Vladimir stereophonic Nerl). The receiver tuning scale is very narrow. - In general, Mr.The price of 380 rubles is not adequate (the average salary is from 115 to 200 rubles per month)

Aelita-111, (sorry 102) Riga's younger sister in an ugly brown case, even heavier than Riga, with a hitchhiking board in the entire case - but the tape recorder and receiver worked fine.

Micro-assembly, very unusual in design, in an aluminum "case":

Purpose - transformerless DC voltage converter (capacitor multiplier) with stabilization for power supply of varicap matrices in electronic tuning units for electronic equipment of wide application.

The microassembly was developed for the radio tape recorder Riga-111 (ML-6102) at the Orbita design bureau of the Radiotekhnika software. Lead development designer - A. Goryunov. The microassembly replaced the PN-15 unit used in previous models of equipment (Riga-104, Salyut-001, Riga-110). It was first produced in the RRR microelectronics shop, then, before the production of the ML-6102 radio tape recorder (1991) was completed, at the Elmira plant (formerly the Riga experimental plant of functional microelectronics) by Radiotekhnika PA.

Microassembly was also used in a copy of the Riga radio tape recorder produced at the Kurganpribor plant under the name Aelita-102. Microassembly was also used in the Medeo-102 radio tape recorder produced by the Petropavlovsk radio plant named after V.I. Kirov.

Here is a note about this micro-assembly from the magazine "Radio", No. 7 1984. :

As a power source for the varicap matrix in the electronic tuning unit of the radio receiver, the 04EM002 microassembly has a number of advantages over the PN-16 unit that is currently widely used for this purpose. It is much smaller in size and weight, has a reduced level of electromagnetic radiation, no high-pitched sound accompanying its operation, three times higher efficiency (70%), and expanded limits of supply voltage and operating temperature make it possible to use the microassembly in car radios.

Structurally, the microassembly is made in the form of a board with components manufactured using hybrid integrated circuit technology. The board is placed in an aluminum shielding casing and sealed with a compound.

Functional diagram and a typical diagram for the inclusion of a microassembly:

The voltage converter consists of a multiplier containing a seven-section diode-capacitor circuit with a capacitor recharge control unit, and a negative feedback circuit to stabilize the output voltage.

External capacitors are used to smooth out voltage ripple at the input and output of the microassembly.

The microassembly allows operation while maintaining electrical parameters at temperatures from -25 to +55 ° С (transportation and storage at temperatures from -50 to +60 ° С), under vibration loads at frequencies up to 60 Hz with a maximum acceleration of up to 5 g and in conditions of high humidity up to 98%.

The electrical parameters of the microassembly are summarized in the table:

Contact someone who understands, otherwise there will be more broken parts after your repair, not less.

But if there is an irresistible desire to delve into the guts of the tape recorder, check the power source, measure the voltages at the electrodes of the power amplifier transistors and analyze the measurement results, they will most likely suggest a way to fix the malfunction.

Maybe all the same RM-204C? My uncle assembled an amplifier from this device according to the scheme from the Radio magazine, squeezed it into a Chinese radio tape recorder in place of the burnt out UMZCH. Still gathering dust somewhere in the mezzanine

According to the diagram: first of all, check the power source, on the diagram I marked the points in red between which the voltage should be measured. The voltage should be between 12-14 volts.

Aelita-63 1968, gasoline engine 1.6 l., 80 hp sec., rear-wheel drive, manual transmission - owner review

In 1963, the Alma-Ata engineer-inventor Vladimir Vasilievich Smirnov began to design his concept car.Aelita-63 white in a two-door body of a convertible went with the plates "PROBE" instead of license plates in accordance with the rules of operation of vehicles of that time (with regards to prototypes and homemade products). The car was built on the basis of Moskvich 403, on its chassis.
In 1968, Smirnov successfully tested the second version of Aelita - 6302 - a fiberglass monocoque coupe body on a space frame with an all-metal fixed roof. Apart from the presence of a roof and a frame, it differed from the first version by the radiator grille, the shape of the fins of the rear fenders, the engine, the interior solution, and the chassis - this time the coupe prototype was built on the basis of the Moskvich-408I car.

On June 3, 1974, Smirnov receives a special ATE certificate (ATE is an act of technical examination of a non-factory prototype), and on July 3 of the same year, he undergoes a technical inspection at the traffic police and receives a license plate 73-35ATL and an official registration certificate for his concept car.

The author of this amazing car is V.V. Smirnov was a legendary person at one time. Having many medals and diplomas of the All-Union Exhibition of Economic Achievements of the USSR, being an engineer-rationalizer, designer, head of the general technical design laboratory at the Central Station of Young Technicians of the Republic of Kazakhstan, he was the ideologist and inspirer of TsSYuT. From his youth he devoted his whole life to inventive and creative activity, and later to teaching work with young people. In the early 1980s, he was the deputy director of the CSYT for educational work, and later became the director of the CSYT of Kazakhstan, having worked in it until its disbandment and closure in the 1990s. Smirnov and his work at TsSYuT in the 80s were repeatedly written in such legendary technical journals as "Modelist Constructor", "Young Technician", "Tekhnika Molodyozhi", "Science and Life", "Inventor and Rationalizer" ...

The cassette recorder Radio engineering ML-6102 has been produced since 1988 by the Riga Radio Plant named after A.S. Popov.

The first two prototypes of the Kurgan radio tape recorders are on my conscience. Their initial name is “Orpheus-301”.
The first model - a mixture of the Meridian receiver and the Vesna-306 tape recorder, we built together with Volodya Karpenko in September 1976, in a round-the-clock operation. The first one - in a month (total). Second -
for a couple of months, already in more similar to "Hrundig" - in November-December. Further - on the development of Crooklis.

there is no great reason to reject, I am already 70 years old, and nothing is left of “Kurganpribor”.

Before "Aelita 101" (at the beginning of "Aelita-201") there were other variants of the 3rd class developed by the Riga designer
Kruklis, but the Riga design bureau Orbita and Rigas Radio Rupnitsa (RRR) insisted on the 1st class apparatus - Aelita from Kurgan and Riga from them. "Aelita 209" their development with our modifications.
And the people of Kiev in those old years were leaders in the production of measuring magnetic tapes. We adopted something from them and adjusted our own. But this is already technology.

I did not carry out prophylaxis, only changed the belts in brown, and restored the preamplifier to work in black. Small surveyor.
Music

and where to buy such a whole worker. brown aelita 102 memory of childhood.

PImkerton: Look on Avito, they are quite often.

Super cassette recorder at the time. Produced in Latvia. Everything was in it and at that time it was only possible to dream of such a thing!
It cost 330 rubles in 1986.

Murad Ramazanov: Thank you, Murad, I agree with you, it's a pretty sophisticated unit. The only negative is monophonic.

Aelita-101 looked more canonical, perhaps. But they are even rarer now. The pop VEF-260-2 looks more fun in comparison with Aelita-102 :).

excellent technology, it was so brown, by the way I used up the batteries sparingly

2 such receivers in Riga 110 work, only in Moscow, they are silent in the countryside,

I just wanted black, from my musical childhood!

I have already sold the black one))) I don’t want to sell the redhead, unless someone offers a GOOD price!

It falls short of the first class. I mean the sound is floating on the second tape recorder. All chrome, probably at the factory, was handed over to precious metals.

My friend had one like this at the beginning of the 80s (from 82-83 years), played very decently cassettes and caught the radio very well, only she had a weight - Mom, do not worry. she was not inferior in size, the Japanese woman played louder in sound, but there were few low ones, here Aelita won. A very successful model, if she had a stereo price, she would not have been. All romantics, electronics, springs, etc. were inferior to Aelita in everything.

I don’t know of course, but, IMHO, this Electronics 302 “Olympic” in dark brown looked festive, and this bandura looks like a huge pile of shit (((

John Prostov))) Figuratively! An interesting metaphor!))) Even such a comparison did not occur to me!))) They smiled!)

The radio tape recorder is screaming very loudly! Super! 🙂

Riga was a very pleasant device.And pretty enough. With chrome elements on the front.

There was also exactly the same name Riga.

For a hike, this later version was the first one with a large number of chrome-plated overlays. The brown one, of course, looks awful. But this radio tape recorder played an awful lot, it had a very soft and large imported speaker, I don’t remember I can be wrong

sorry i messed with aelita 101

I will not argue, but my friend's I already said aelita was somewhat different and there was a gdr ev speaker like

discoman80 The speaker is indeed very successful - a large oval three-watt broadband speaker with a shielded magnetic system. But not imported, but domestic - this was used in top-class receivers "Leningrad-002", for example.

What a horror and not a radio tape recorder, I do not know how the sound quality in real life (although you can hear from the video that it is not very good) and work, but the plastic is kind of shitty in appearance, as if it was molded from plasticine and the design seemed to be made for use somewhere in a mine or in the workshop, so that it would not be a pity to get it dirty, the battery compartment lid seemed to tell us “don't even try to put batteries in me”. Although, of course, for the beginning of the 80s, such devices were quite normal, although the West, of course, these years produced much better and more beautiful radio tape recorders.

Alex sambo
You are wrong, this Aelita 102 radio tape recorder was of very good quality. There were many operations in it, which was not in other radio tape recorders! I bought it in 1986 in Kazakhstan, it cost 330 rubles. Then it was very expensive and not everyone could buy it. The sound quality was excellent. I would still buy it by now, they are on sale!

And the weight, by the way, may turn out to be enough. if, for example, you need to fight off hooligans!) In general, I find pluses in the brutality of the device.

Normal design for the late 70s, foreign counterparts externally differed little. Sound quality is like any portable, no better or worse. Among the shortcomings are weight (it can be wearable only conditionally), reliability (they did not live for a long time) and inadequate price.

Alex Sambo I agree, the design is brutal. ))) Perhaps too brutal)). Sblrki weaving is blatant. But a lot of interesting ideas are laid
But the implementation is as always. ((

Sergey, excuse me for the inappropriate question, you have a lot of interesting videos with an overview of electrophones, radios, tape recorders, etc., including photographic filming equipment, my wife and I watch them with curiosity, and why do you always bypass cinema projection devices ? There are very few useful videos on the Internet about such legendary devices as Russia, Rainbow, Ukraine, etc. I think it would be pleasant for everyone to see in your performance, it is possible to learn something new about our domestic film projectors and their use in everyday life. So I know that, for example, an amateur cinema projector RUSSIA was once produced in your city. Best regards from Tambov!

Vitaly, thank you for your comment and an interesting question! I am going to shoot some reviews on amateur cinema projection technique. The collection contains eight-millimeter film projectors Luch, Volna, of course, and Russia too. I will certainly take it off and post it on YouTube, stay in the channel, please! There will be a series of videos about movie cameras and projectors.

Before searching for a breakdown, make sure that there is voltage, there may be no voltage and there is a reason that the fluorescent lamp does not light up. If this is not the reason, we look for it in this order.

turn on the light and nothing happens;

the bulb glows only at the edges;

the light is flashing with a strobe;

the starter is on and the lamp does not start.

Please note that manufacturers recommend replacing fluorescent lamps and starters at the same time.

she flashes a strobe;

the edges of the flask are black;

it glows, but the brightness is not enough (it shines weakly);

the lamp does not work.

A typical breakdown of budget luminaires is destruction of lamp holders and loss of contact. High temperature of a closed luminaire, the cause of destruction of plastic fasteners and connectors. Replace them if possible, bend the contacts if the condition is satisfactory.A possible malfunction is a burnout of the choke, often this breakdown is visible visually, a changed color, a melted terminal. Image - Aelita 102 DIY repair

If you do find a malfunction, you will have to replace the choke with a working one to repair the lamp. You can check the performance with a multimeter, the resistance of a serviceable one, in the order of 30-40 ohms. Make sure the choke is not short-circuited before placing the lamp in an inoperative lamp. Otherwise, you will lose a worker too.

Sometimes there is a breakdown in the wires - the vibration of the lamp breaks off a core near the lamp holder or choke. In this case, repairing a fluorescent lamp is reduced to restoring contact. The owners of the old-style lamps bypassed these malfunctions.

If you have a lamp with electronic ballasts made in china and replacing the light bulb did not solve the problem, most likely the problem is in the electronic unit.In most cases, you can fix it yourself with a soldering iron and a multimeter at your disposal. Below we will take a closer look at how to repair the electronic ballast of a fluorescent lamp with your own hands.

Now we will look at the main malfunctions that can be eliminated without much investment. Let's start with electronic ballast, because in its circuit there are a lot of elements that can fail, and besides, tubular fluorescent lamps with electronic ballasts are more common today.

The most common failure is transistor breakdown. This breakdown can only be determined by removing the transistors from the circuit and checking them with a tester. Overall transistor junction resistance

400-700 Ohm. Burning out, the transistor pulls a resistor in the base circuit with a nominal value of 30 ohms.

There is also a fuse or a low-resistance 2-5 Ohm resistor on the board, most likely it will have to be replaced, which will end the repair. You may additionally have to change the diode bridge or its elements.

Rarely is the breakdown of 47n film capacitors (microfarad floor) or a resonance capacitor in the filament circuit. There have been cases when all of the above is intact and in good order, but the lamp does not work, the reason lies in the DB3 dinistor. If you checked all the elements of the circuit, then try replacing the dinistor.

Perhaps you decide that it will be cheaper to buy a new electronic ballast than to repair a broken one. Replacing the starting equipment should not be difficult, because the connection diagram is applied to the device itself. Upon close examination, it is easy to understand, L and N are terminals for connecting to a 220V network.

We also recommend watching a video that clearly shows how to repair the electronic ballast of a fluorescent lamp yourself:

We draw your attention to the fact that this technology can also be used to repair the CFL energy-saving light bulb. For example, if one heating burned out, the repair is the following procedure:

If your old-style lamp does not light up and you are sure that the reason lies precisely in it, the first thing we recommend is to check the starter. The easiest way to check is with a working starter with the same characteristics on hand. However, if no suitable replacement device is available, then a functional test can be carried out using an incandescent bulb with a socket. Everything is quite simple - we connect one wire from the cartridge directly to the outlet, and the second through the starter, as shown in the photo below:

If the light is off, then the reason is in it. Instructions for replacing the starter of a fluorescent lamp are clearly provided in the video:

The choke can be checked with a multimeter by ringing its winding. If the choke is really out of order, then the repair of the fluorescent lamp comes down to the fact that you just need to change the choke for a whole one.

Here are the main malfunctions that I personally encountered and successfully eliminated. Following our algorithm, troubleshooting will take a little time and returning the lamp to work on its own will be a couple of trifles. We hope our DIY fluorescent lamp repair instructions were clear and useful for you! Be sure to watch the video tutorials, because they go over in detail all the steps to fix a broken light bulb.
