Gold in diodes and zener diodes of the USSR. Overview.
In this video, I will analyze several diodes and zener diodes from the times of the USSR. I'll show you how to disassemble them best, and where the gilding is. In addition, in the second part of the video I will show a board with buttons from an old American-made pulse generator. Earlier, when I analyzed it, I did not find anything useful on this board. However, after some time - I already looked at her with different eyes ... What happened next - you will see by watching the video to the end.
