so I tried removing it from the socket and replacing
it with a 2500ohm non inductive resistor then I tried to probe the output
port. I think this didn't show me the correct values.
Wrong method. You replace the tube with a mica capacitor simulating the
output capacitance of the tube. Then you can adjust the tank tap
positions using a dip meter.
I think you really need to read up on power amplifier design. One of the
best books is Radio Handbook by William Orr, W6SAI (SK). It is out of
print but usually available on eB... I think the 23'rd edition was the
last and latest.
