Hi Carl, and all that gave some advice.
Its good I have some things right!The amp has its 813`s in a box
formation with bases 1/4" lower than deck on pillars with a gap around
valve envelope.Below deck I have a 4"PAPST fan blowing over heater choke
and venting around bases.the grids are straped together with 3/16"brass
strip and will now finish the job off.
The amp will be for 160,80,40Mtrs Anode volts will be around 2,800 volts
with around 1 amp rating on xfmr.
But I`m taking my time with it!
PS at 2.8Kv you only live once,so get it right
Regards Jon
