Terry:

It's been a while since I've owned an Omni 6, but removal of Plug 52 should 
have no effect on pilot lamp brightness.  Removing the plug disables the 
side-tone wrap-around circuit -- a cause of clicks, but not audible thumps. 
If thumps are bad enough, they may be masking any benefit of the Plug 52 
removal.

I also do not know if Plug 52 was re-numbered beginning with factory Omni 6+ 
units (not "plus" upgrades).  I would check the schematic to ensure that it 
is right circuit being disabled.

Does the headphone audio thump change with RF output power level?
