So what do you do to Q12 on a TRC-422A?
Q20 on a TRC-428?

What to do with adjustments for trc-482?
Realistic TRC482: {L304, L305, L306, L307, Q201}

I know you can also cut d208(audio limiter)
 
Thank you.

That says L26, but is is beside the finals and filled with wax. Is it part of the TVI/harmonics filtering that gives ghost watts or is it a legit adjustment?
 
Yeah, I wasn't sure if that is part of the trap it not. It's a plastic piece with wire wound around, and a ferrite screw inside for
adjustment. Being waxed like a couple cans and the trap "bare wire" windings people love to spread, I figure is is part of the trap.

What is the difference between AMC and ALC?
Click to expand...
AMC = Automatic Modulation Control (adjust to no more than 100% modulation). Most radios power supplies and mod transformers can not even hit 100% well without severe distortion, ie splatter.
ALC = Automatic Level Control (You need a scope to adjust properly on SSB)
Note: Simple power meters are totally insufficient for ANY adjustments, including RF power out/dead carrier.
