Ремонт осциллографа С1-93

A video about a minor repair of an S1-93 oscilloscope. Sometimes frequently, sometimes rarely, I could hear clicking sounds coming from the oscilloscope's housing, as if something was clicking. Therefore, I made the difficult decision to disassemble this marvel of Soviet and post-Soviet industry, and at the same time demonstrate how to disassemble a Soviet oscilloscope and try to find the source of the clicking noise. The cause was found, and the oscilloscope was repaired!
