Boards from which valuable parts are cut off are also bought from 70 rubles per kg. Boards from which valuable parts are cut off are also bought from 70 rubles per kg.
Assemblers of radio components know that among Soviet products there are often those that cost really good money. These can be GMI generator lamps , worth up to 15 thousand rubles in purchase and palladium capacitors of the KM series up to 200,000 rubles per kg. and rheochord threads and much more.
At the same time, many also know that although the Soviet electronics industry continues to feed many of us today, there are many products in it that are not worth a penny!
This is a big problem, because many beginners unknowingly accumulate radio components for years, which then absolutely no one wants to buy.
In this regard, in my opinion, it seemed absolutely logical to create your own list of radio components that are not accepted for sale, but that beginners love to collect so much.
I would like to immediately note that, due to the peculiarities of my character, I try not to throw away even those products that do not represent either material or technical value. I just like different parts, so I don’t throw them away — I save, maybe they will fit. Yes, and it’s a pity to throw them away, their shapes are so bizarre that if there was an Oscar for the most beautiful detail, Soviet generator lamps, gold-plated microcircuits or boards with millions of tracks reminiscent of the routes of futuristic cities would definitely get it.
TV lamps. Not accepted. Buy only restorers. Generator lamp GMI-11. Contains precious metals. TV lamps. Not accepted. Buy only restorers.
Despite the fact that in some radio tubes you can find «mesh» of gold and parts that have a deep silver coating, most of them are still completely useless and do not represent any value other than aesthetic.
Lamps that contain gold or other precious metals are extremely difficult to find and many of them were not used in civilian technology, such as color televisions or stereos.
Expensive lamps are, first of all, generator lamps . Cheap — indicator .
In a simple technique, there were lamps that are not in demand anywhere now. There is probably no point in collecting them, but I would still advise you to check the content of precious metals in the directory before throwing them away. Well, do not forget about the bulletin boards, sometimes restorers are happy with such gifts. I try my best to save those details.
Film capacitors, popularly «Aluminum barrels».
Aluminum K50 MBM Silver-tantalum K52 Aluminum K50
90% of aluminum capacitors found in Soviet electronics are only suitable for delivery to non-ferrous metals. And then, provided that the insides are “gutted” from them.
With the cost of aluminum at 60 — 80 rubles per kilogram, it is not always prudent to parse such parts. However! Among such capacitors, there are those that cost quite good money and contain not only silver, but also tantalum that has risen in price in buying up.
These capacitors include products marked K52 and some K53 models.
Outwardly, they can be confused with aluminum, such as K50 or MBM. But unlike film and x, the price is several times higher than the cost of non-ferrous metal, and the mass of silver can reach 7 grams.
K73-17 and K71.
K73-17 K71-7 K73-17
Many beginners were seduced by the external dimensions and conditional rarity of radio components with the designation K73-17 or K71. First of all, their similarity with palladium capacitors and their infrequent appearance on boards are misleading. However, to the great regret of many gold miners, the content of precious metals such as gold, silver or platinum group metals in capacitors K73-17 and K71. Equal to zero!
MLT orange. Meet with the content of silver. MLT orange. Meet with the content of silver.
Probably every beginner has come across these insidious, barrel-shaped radio components. You open the directory, and you see that most MLTs contain a significant amount of silver , but when you bring them to buy up, they refuse to buy them. The reason lies in the fact that it is not easy to get this silver from the MLT , and not all models are silver-plated.
The list of non-receiving radio components can go on forever. Believe me, there are more than enough of them. However, for those who are just starting to collect radio components for precious metals, I would like to say that there were times when tantalum capacitors were not accepted, but now they cost good money. Therefore, it is possible that the time has not yet come for these parts and it is still not worth throwing them away?
