Need help with Thereminvox

Hello! I'm new here and I decided to make my own Thereminvox by myself.
It's the first time for me, so I would appreciate your help.
 I have chosen to use Korolev's scheme
(http://rghost.ru/50409160  http://rghost.ru/50409205  http://rghost.ru/50409224)
and I'm just wondering if I could buy all the components for this scheme in your store
and may be get some advices.
Thanks in advance, Evgeny.

Hello Evgeny,

most active components (semiconductors=transistors and diodes) in Korolev's circuits are Russian components from more than 40 years ago. If there is still a way to find them, it will be in Russia.

Sure, for most Russian semiconductors (many of them were plagiats from Western components) there existed a Western equivalent in the time. But these are also outdated and not longer produced.

Thus you should perhaps find an older competent Russian electronics engineer who is still familiar the ancient Russian components and who can after thorough analysis of the circuits point you towards modern equivalents.

Blin, Evgeny, this is not a store of electronic components. This is a "free shop" of ideas, experience sharing, knowledges, advices etc. Plus, you did not ask the specific questions like "what type of T1 can be used". Your plans are not clear, whether you want to use the authentic (russian) components or their modern Russian/Western/Chinese equivalents.

If the Russian is your native language, the best place I think is any of russian electronic forums, where the local coryphaeus can give the best advices about suitable substitutions.  And many of them would be glad to get rid of trash.

КП303Б ( <$1 in low quantities ) = 2N5556

KT3102AM  ( <$0.2 in low quantities ) = BC547 and so on....
