Funny thing is the Soviet transistors of same vintage seem to be bullet proof in comparison, at any rate the ones I have come across - and you can still buy them quite cheaply.

I have found old Soviet components to be reliable, only having one transistor faulty so far (I have also used quite a number of valves). I do wonder whether, even though their temperature range specifications etc may be similar to UK / US and possible temperature variations the same their approach may be to expect far greater misuse and variations than in the west. I know with the Russian multimeter that I have had for years has had stress that I have not seen AVO's survive and still keeps going.
