[Amps] Low power output from 4-400A Amp.

[Bruce Lanning]

Again, I want to thank all who responded to my inquiry as to the low output 
on my 4-400A amp. I have found the problem... My Plate and Grid current 
meters were wired in error. The grid meter was tied from Gnd. to the plus 
side of the plate current meter in the cathode circuit. The Plus side of the 
plate current meter went to the cathode and the minus side went to B-. This 
was in effect of putting the two meters in parallel. After connecting the 
grid meter plus terminal to B- the Plate current now reads correctly and all 
is well. Thanks again all.
