I basically follow the recommendations by F J Camm on the voltages of coupling capacitors, smoothing capacitors and HF or AF bypass and so forth. His books are around 1940's period. There is a very good chapter called Correct Component Values and all the recommendations were contemporary with the era (which I like). I would like to get hold of His Superhet Manual as well at some point.
The technology in Russia today in its application to "dated" engineering has been very useful to me. I've had to spend a lot of time researching the availability of tubes. The 6U8A had me a bit interested last night - seems a bit more scarce. In Russia the perspective is neither "valve" nor "tube" but they tend to go with "lamp". For me the main consideration is finding decent prices or matches. Hopefully my site will creep up on Google once I sort out the listing process. Still, yes, I'm very active in electronics and mechanical engineering at present.
