playing with russian ROD valves.

[ruben]

I have tried the valves "on air" on a circuit strip board, because I don't have a copper board on hand. I know, it's not a good approach with high frecuency, but as a "transistor" man, I was thinking that is enought for a first try.
So I will made the whole circuit again with better layout, shorts legs, and with some screen on valves. I have already noted that are very sensible to magnetic fields...

Thanks
