This page contains a List of radio components and products with a photo catalog that we buy on an ongoing basis and in any condition, new and used. On our site, all photos of radio components are copyrighted (a lot of time was spent creating them, while our competitors were just making money) and are not copied from free sources on the Internet, like some bureau sites for buying radio scrap at a reduced price, widely advertising themselves as "large and respectable", but not wanting to take "some kind of photo of radio elements" and exposing super-mega unrealistic prices higher than the London Stock Exchange by 30-100% for stolen photo parts.
Below the photo catalog is "", where information is given for each series of radio components, that is, what value these radio components represent.
It should be noted that this list is far from exhaustive. We are trying to add new purchased items to the list, which is reflected in our catalog with photos and prices for expensive Soviet and imported radio components in the relevant sections of the site.
Sell valuable USSR radio components for radio, new and used, containing precious metals for favorable prices For today, you can contact . For more than 6 years we have been cooperating with private individuals, reliably. The exact cost of Soviet radio components depends on the quantitative content of precious metals in them, the year of manufacture, acceptance conditions (military or civilian acceptance) and the manufacturer.
It also buys modern radio components of imported and domestic production: capacitors, microcircuits, transistors, connectors, relays and other electronic components.
Domestic and imported production containing precious metals.
there are many valuable radio components in televisions made in the USSR. In fact, and in most cases, you can find there several pieces of green KM5 capacitors, less often red KM6. As well as several KT-203 transistors, which cost 5-6 rubles each. Perhaps if the TV is from the 60s and 70s, you should pay attention to the lamps.
So you are on the right track and disassembly, in order to extract radio components, you can begin.
You should also pay attention to such parts and components with white contacts:
Information provided by Valery F.
He handed over to the scrap only failed. The hand did not rise to hand over live radio components for tearing into scrap. Therefore, I recommend using precious metal content tables only to account for the amount of gold, silver, palladium, platinum, tantalum and other precious metals in write-off devices.
The reference book contains detailed tables of the content of precious metals in various radio components: microcircuits, transistors, relays, contactors, switches, diodes, thyristors, triacs, capacitors, variable and fixed resistors, lamps, connectors, kinescopes, quartz and many other domestic radio components.
Scrap of various radio components contains different amounts and types of precious metals, for example, semiconductors and connectors most often contain gold, fixed resistors - silver leads, military acceptance variable resistances contain palladium in contacts, relays, contactors, switches, etc. switching devices may contain silver, palladium, rhodium, iridium, platinum, gold, tantalum electrolytes (electrolytic capacitors) - tantalum, and gas-discharge and electrovacuum devices can contain almost the entire periodic table - gold, silver, palladium, rhodium, iridium, platinum, thorium, rhenium, tantalum, tungsten , molybdenum, nickel, cobalt.
Dear Internet Users! Send us your photos and notes about where and in what devices you met radio components containing precious metals.
The list of decommissioned and subject to disposal devices, various blocks and radio communication units, with the content of precious metal in radio components and electronic components in its composition, is simply huge. Ever since the collapse of the Soviet Union, when everything and everything collapsed, when chaos and confusion reigned in the country, salaries were not paid, and many, in order to earn at least some money and feed their families, brought home and then dismantled various decommissioned electronic devices with institutions and organizations. Until now, such devices are still gathering dust and waiting for their fate in garages, cottages, and sometimes in the open air, covered with corrosion. Well, let's start with the most common.
Let's say right away that almost all radio components are on the boards. Transistors KT-803, KT-808, KT-809, KT-812, KT-908, KT-912 are usually located in the back of the devices on aluminum radiators, transistors KT-911, 2T-911B are located on an aluminum base, for heat dissipation, on the board.
Switches 11P 3N are attached to the case, and resistors PTP, PP3-41, PP3-43, PP3-47 can be located on a metal base inside the unit or attached to the device case.
Therefore, you first need to find and disassemble the device or unit, remove the boards, and only after that get radio components with precious metal. We must be ready for this. There is an opinion that
there are many valuable radio components in televisions made in the USSR. In fact, and in most cases, you can find there several pieces of green KM5 capacitors, less often red KM6. As well as several KT-203 transistors, which cost 5-6 rubles each.
Perhaps if the TV is from the 60s and 70s, you should pay attention to the lamps.
You can spend a lot of time disassembling such a TV, not to mention the size and weight of the TV itself. For radiograms, tube receivers, tape recorders, the situation is similar. Quite a lot of KM6 capacitors are red, less often green in Soviet VCRs of the VM series. Also there are yellow and blue ceramic capacitors K10-17.
Record holders for the content of precious metals, of course, are computer systems, automatic telephone exchanges and special electronic devices manufactured in the USSR.
But, unfortunately, such computing systems are very rare nowadays. So thinking about where to find them can be left and forgotten. The most important thing in this business is attentiveness. Radio components can sometimes be found in inconspicuous metal boxes and blocks. If you find a metal box with these connectors:
So you are on the right track and disassembly, in order to extract radio components, you can begin. You should also pay attention to such parts and components with white contacts:
Many radio components with precious metal are found in measuring, computing devices, such as: high-frequency generators, frequency meters, frequency synthesizers, electronic voltmeters, oscilloscopes and other devices. The density in such electronic devices is very high. But all the same, they need to remove their protective cases and see what is inside. Sometimes almost nothing.
The measuring devices and devices listed above, of the initial series and the first modifications, practically do not contain radio components with precious metal. These devices are distinguished by their large size (both the case itself and individual knobs, switches, and other parts) and weight.
Such devices contain powerful transformers - this partly explains the large weight of the product. Therefore, when disassembling such devices, it is first better to look at the table of the content of precious metals in devices in order to have an initial idea of \u200b\u200bwhich device you found and what can be extracted from it.
Sometimes you can find devices and devices that are not
a hand will go up. They contain little precious metal inside, but as a product, they are of value to radio amateurs. Therefore, you can always try to find a person who will buy this device in working order. Or just don't break it. From the point of view of a radio amateur, disassembling devices and handing over radio components for scrap is perceived extremely negatively and many unflattering words can be heard about this.
Radio amateurs with great experience treat radio components in a completely different way. For them, each radio component is of real value, whether it is a microcircuit or a transistor, and is sometimes perceived as an inspired object. The current younger generation, in most cases, perceives radio engineering and radio electronics produced in the USSR, like a gold digger riverbed.

This article serves as a help for customers who find it difficult to find radio components to be bought up in order to extract precious metals. As you know, the highest concentration of expensive components is concentrated in Soviet-style military equipment. But few people realize that a significant proportion of precious metals is contained in the radio components that were used in the assembly of Soviet household appliances.
During the existence of the USSR, the domestic industry produced two types of televisions - tube and transistor.
In this case, tube TVs are very scarce in terms of the content of precious metals, in particular, only the output beam tetrode, marked as 6P36S, 6P44S, 6P45S or GU50, is of value. That is, it does not make sense to engage in a special search for this technique. unless it happens to be handy. But transistor models are stuffed with precious metals more generously, since it is transistors of the KT 502-503, KT-310, KT-814 and KT-940 brands that contain precious metals, in particular, gold and silver. Some TV models in small quantities are endowed with green and red KM brand capacitors, as well as yellow K10-17 capacitors.
Soviet-style computer technology has always been crammed with various kinds of precious metal-based components, and calculators are no exception. In particular, in Soviet calculators you can find expensive green KM capacitors and K140UD microcircuits. In addition, the output contacts of the calculator boards, connectors and switches also contain gold and technical silver.
Unlike calculators, Soviet computers contain a larger number of green KM capacitors, as well as yellow K10-17 capacitors, that is, when disassembling Soviet-style computer equipment, you can provide yourself with a very tempting amount of money. A nice addition is a number of plastic chips, the inner filling of which contains gold.
This category of technology does not have a rich content of components, however, such units are available everywhere, and disassembling them allows you to get hold of not only a certain amount of non-ferrous metals, but also components such as relays, thermostats, and silver-plated contacts.
In the manufacture of electronic equipment, precious metals can be used - gold, silver, platinum, palladium. The content of precious metals in radio components produced in our time is very small, however, many elements of old equipment, especially from Soviet times, can contain precious metals in fairly substantial quantities.
In the manufacture of electronic equipment, precious metals can be used - gold, silver, platinum, palladium.
With this in mind, do not rush to send your electronic equipment to the landfill, it can still bring you profit. Knowing which radio components contain precious metals, you have the opportunity to earn quite serious money.
Precious metals contain many radio parts, including:
Of course, precious metals are not contained in all connectors, microcircuits and other radio components, but only in some types. Even in the same details, which include precious metals, their number can vary greatly and depends on the year of issue. That is why radio components have different values, directly dependent on the content of precious metals in them.
The main value in this regard is the electronics of the Soviet era, namely computer blocks, various military equipment. For example, in the computers of the EU series, famous at the time, the content of precious metals can range from several hundred grams to 10 or more kilograms! Given the current value of gold and silver, dismantling and handing over this electronic equipment to a specialized company can bring more than a significant income.
Approximately half of all the gold and silver used in the manufacture of electronics was spent on making contacts and connectors. These precious metals provide very high-quality contact, which determined their wide application. Usually, the base of the contact was made of a copper or brass alloy, only the pads themselves were made of precious metal.
The rest of the gold and silver is found in microcircuits, transistors, variable resistors and other electronic components. Precious metals such as platinum and palladium are mainly found in ceramic capacitors.
Some radio tubes contain a large amount of gold - for example, the GMI-19 lamp contains as much as 16 grams of gold! Many other radio tubes also contain gold, silver and platinum, but the amount of precious metals in them is usually quite small and usually amounts to thousandths, less often hundredths or tenths of a gram.
The content of precious metals in radio components, as a rule, is low, which significantly complicates their extraction. Only in rare cases can you directly extract the precious metal from an electronic component - for example, bite off gold or silver contacts. It is impossible to extract precious metals from microcircuits, transistors, diodes and other electronic components in the same way.
That is why, in the overwhelming majority of cases, precious metals are extracted from electronic components at specialized enterprises that have the necessary equipment and technologies. At the same time, raw materials are supplied to enterprises in an already prepared state, sorted into specific groups.
The finished raw material goes through several stages of physical and chemical processing, during which the concentration and isolation of precious metals takes place. All these processes are quite complex, so it is almost impossible to carry them out on your own at home. In addition, large volumes of raw materials are required, which are very, very difficult for a private person to collect.
Taking into account the difficulty of extracting precious metals from radio components, this work should be carried out only at specialized enterprises.

The transistor is the most common component of electronic technology - the basis of any microcircuit. In only one processor of a modern laptop, their number exceeds one and a half billion pieces and continues to increase every year. Radio components such as the transistor are the most common of this group.
History reference
December 16, 1947 Walter Brattain and John Bardeen made the first model of a point transistor. This date is considered the birthday of the transistor. In 1956, Bardeen, Brattain and Shockley were awarded the Nobel Prize in Physics for this discovery (William Shockley created the theory of the p-n junction and the planar transistor).
The beginning of the use of gold in the transistor falls on the end of 1958, when the alloying of collectors with gold (Jean Erni) began to be used in transistor production technology. It was a breakthrough in transistor technology.
How many precious metals are in transistors
The use of precious metals in transistors is determined solely by technological necessity. With the expansion of knowledge about the physics of metals and the development of new technologies, the proportion of precious metals in transistors is constantly decreasing. The maximum content of precious metals in radio components and in particular in transistors falls on the middle of the 60s and until the end of the 80s of release. So the gold content in some types of transistors can reach up to 2.5%.
All these components are valued at DETALTORG and we always buy radio components from the 60s - 80s, offering a high price for them.
More gold and silver are used in military grade transistors. Distinguishing transistors for general use from the military is simple. For military acceptance, the marking begins with a number, for example: 2T342, 2T912, and the designations for general use, respectively, are KT342 and KT912.
But this statement is not a rule. We can only say that from the entire list of transistors in one product with military acceptance (marking starts at 1, 2, 3), gold and silver contain on average about twice as much as in a product for general use.
You can get accurate data on the content of precious metals in radio components and their price from us at any time - call us, write to us.
Summarizing, we can only say that the content of precious metals in transistors is distributed on average as follows:
We emphasize that these are averaged data and for some series of transistors these values differ significantly from those given, and in some series there are practically no precious metals. For example, in KT315, KT316 the gold content per 1000 pcs. is 0.07 g, and in KT966 gold 29.11 and silver 58.03 g.
The table shows the content of precious metals in transistors, the value of gold in which is higher than 50 g per 1000 pieces.
