A few weeks back I asked about reconnecting a 4-1000....
Currently the amp is connected GG, both the screen and the grid strapped
directly to the chassis.
Many differing viewpoints were offered on how I may increase the output of the
amp, easiest being to raise the plate voltage.
However, I have no budget for a new power supply.
I believe I shall try this.
Disconnect screen and grid straps,then place a 650 pF, 18kv doorknob cap
between tube pin and ground.( why 650pF? because I have a bunch of them).
Next is to connect bias and screen voltage at the tube socket.
I will use a regulated bench supply for the bias, and a spare Hi volt supply
(completely separate from the plate supply) for the screen.
Plate supply is variable, up to 4.5kv.@3A (big iron from old A.M. station)
Cathode drive will be retained.
Any comments? Any obvious faults to my logic?
