Byron -
This works well, just be VERY careful removing the screen voltage from
the Final IF you are unsoldering from the feedthrough capacitor on the
shield wall. They are susceptible to overheating, and cracking, if too
much force is used when removing the wire. Not fun to replace, either!
Of course if the transverter mod has been installed, just "pull the plug"!

Hello-
I neutralize my Drake's by:
1. Disconnect screen voltage to finals.
2. Tune up transmitter PA as normal on 10 meters into a dummy
load, although there is no discernable output on wattmeter. Listen to
the signal on a receiver. Tune up transmitter for max signal in
receiver. Adjust receiver gain to prevent overloading.
3. Adjust neutralizing trimmer for minimum signal as indicated
on receiver S-Meter.
4. Reconnect screen voltage to finals.
Hope this is of use,
Byron WA5THJ.
