Yes, that’s what Eimac says typical grid should be. I Eimac also states max limits:
Ig 108mA
Ip 400mA
max output 740W
?
but Heatgkit SB-1000 and AL 80B must have special permission from god. Their manuals say max limits are:
Ig 200mA
Ip 550mA
output 1000 watts
?
To do this, you will need to drive the exciter around 100W and you will exceed the typical 75V grid and likely porn up your 3-500Z.?
In other words, ignore the manual limits and just follow the Eimac data sheet limits and you won’t exceeded your grid dissipation?
