Cabinet made in solid wood machines with CNC with nice copper inserts.
Wow, looks like a brute! Well done! Do you have a schematic? Interesting to see what all those valves are up to.

Hi Tony;
Do you have a circuit for the 813 amp?
I built Peter Millets 813 triode amp using 12HG7's as the single driver..
thanks
Phil

i use the same basic circuit as Pete's minus the computer startup...

2 6ck3's in a hybrid fwb bridge provides about 1100volts at standy..

the 11HM7's has it's own B+ supply at about 440volts dc...

the operating point will probably be at 1kv at 80mA at idle...

Thanks Tony;
My 813 amp runs at 800 volts; i made a regulator to run the 12HG7 but blew it up, so need to remake. at the moment just using resistors to drop the voltage. Would be best to have separate supply.
I don't have the computer startup...

in my case, i added an 0A2 gas reg tube to supply 150 volts to the pentode driver screens, being a separate B+ supply, i felt no need for a regulator to supply this stage...
to me controlling the screen and feeding it off a low impedance source is enough for low distortions, the plates can vary and not have too much effect .....
