Yeah now that I look at the pictures, it's either a 250TH or a 450TH... those are the only tubes that will fit. The 304TL doesn't work because it has a dual filament (4 pin connections).

Hmmm - a 250TH would fit that - only two of the four pins are connected, and the grid and plate caps match the 250's - big plate and 'pin' grid connection. And two of them will do a kilowatt with 3KV on the plates...

Perhaps the Builder will be of assistance. It does look like a nicely-done rig... thanks for the pics!


Cheers
