Could anyone let me know what the specs are on this thing? It's got a
wiring connections guide printed on the side of the heat sink but it's
rubbed off over the years and I can't read it. Does anyone know how to
wire this thing? Any other help you could give on it is appreciated.
Thanks,

I have had aa Federal 5680 triode since 1957. It is probably burnt out, but I don't recall. I was in the Coast Guard on a loran station. we ran magawatt pulses out of a federal amplifier using 12 sets 5680's arranged in 2 sets of six in parallel, as a push-pull circuit. We ran 15.5 kv plate voltage. As I recall, we burned thru these at a fairly high rate. At todays price of copper, I wish I now had all that I threw away
