Hi folks
There is a lot of interest in and use of Russian/Soviet capacitors and valves, but I've never seen any use or discussion of Russian transistors.
Are there any Russian transistors that are worth looking a? I am particularly interested in finding JFET types. There isn't a lot of info online, but it seems that Russian FET and JFET types have a KP prefix.

Well the Soviet block used to buy their FETs from the west for the most sensitive military applications. So the ones now available from Russia most likely are not very good.
It seems that many Russian transistors are germanium based rather than silicon, older technology.
Cheers Jon, that's good to know, I shall avoid germanium.
I just picked up four NOS 6N1P-EV valves for 1 USD on fleabay with 9USD shipping, so hopefully I can also find some Russian transistor bargains, with patience.

Does the Germanium transistor itself decay?
I know the old AC1xx series were notorious for internal shorts, the old 'tin whiskers' problem.
Cheers Alayn. That KD503 sounds useful.
Do you have any similar info on any Russian J-FET types?

KD502 is not Soviet Union, and definitely not russian - it is Chezh Respublic (the country of the former Warsaw Treaty).
Soviet (russian) bipolar transistors are named KT (from Silicium "Kremniy" Transistor).
There are very few good enought Soviet transistors (mostly they are high-freq power fets, KP904 ets)..
I dont know good bipolars (usually they are bad copy of non-Soviet devices).
