playing with russian ROD valves.

Some time ago I picked up and used some Mil surplus guard receivers from Vulcans, they have 9 wire ended valves in the type 6021 twin triodes and 5840 Pentodes, I think 5 of one and 4 of the other.  They are all fitted with small metal screens and heat-sink clips, mainly I would say for dissipating the heat into the chassis more than anything else.  I made a few milli-watt audio amps from them.  was my introduction into valves again.
