П217 germanium transistors - I remember them. They were a top at the П213-П217 range, normally you would be lucky to get hold of 213 or 214. Used them on the last stage of my first audio amplifier.
- kens 4y agoAn interesting thing about these transistors is they look like standard power transistors in a metal TO-3 package. However, the transistor itself is in a round metal package, and the metal flange is separate, and holds down the transistor. Soviet electronics is like an alternate universe where things are similar but also unexpectedly different. (Vintage IBM electronics has the same feel.)
