There were very limited production of amps / set ups in former USSR, but I think you have to find some DIY forum in Russia and start from there, as most designs were not ideal and had their problems.
Like been already said, most talented Russian engineers living abroad now and the new generation of young folks just starting.
Russia and the rest of former USSR parts, didn't had strong general, consumer electronic industries, it's all about black gold, oil and other military shit, the rest, they just importing. I don't believe there will be some kind of boom very soon, as the big boys have their market share there already, but who knows, who knows...
