sure at some point i'll give it a try... i'm thinking i need a way to bias some parallel 6C33's @ -50V or so... they will be running 700ma per pair so the damper diode may not cut it... but with 7.5A of filament and plate current combined... oops.. make that 15A... i forgot i share cathodes :-) thats just a 3 ohm resistor :-) lessee... where on earth can i find a 3 ohm 1KW resistor.... maybe a halogen lightbulb :-) and hmm... a 60V 15A DC supply... hmmmm.... sounds like a concept amp to me :-)
