The procedure to neutralize an amp is pretty universal.

The purpose is to cancel the feedthrough RF from the driver via the Cg-p
capacitance.

Disengage the B+ to the PA (plate and screen for tetrodes/pentodes),
but keep the plate tank connected.

Transmit into a dummy load with power meter inline.

Adjust neutralization cap until tuning the plate tank circuit through its
range causes absolute minimal or no output.

Unit is now neutralized and B+ can be reconnected to the PA and you are
ready to rock!
