In the technical documentation for each device or product, information is provided on the list and amount of precious metals content. The documentation gives the exact weight in grams of precious metals: Au gold, palladium Pd, platinum Pt, silver Ag, tantalum Ta and other platinum group metals (PGM) per unit item. These precious metals are found in nature in very limited quantities and therefore have such a high price.

On our website you can familiarize yourself with the technical characteristics of devices and obtain information on the content of precious metals in devices and radio components manufactured in the USSR. We draw your attention to the fact that often the actual content of precious metals differs by 10-25% from the reference one in a smaller direction! The price of precious metals will depend on their value and mass in grams.

All text and graphic information on the site is informative.
