You have some beads you can install?
I'm just staring at a screen. I don't know what's happening.
You're in charge. Attack from all angles. Ground, beads, shielding.
OK, Here's a picture of the world's smallest 80 watter
TrueThat has to be the worlds worst peice of a crap circuit I've ever seen.....

Lets see...
25w on 3.6Mhz
12.5w on 7.2Mhz
6.25w on 10.8Mhz
3.125w on 14.4Mhz

If we sum all the harmonics up to infinity, I guess I could just about make it 50w.

There is a reason for all the extra solder and flux in the circuit:That has to be the worlds worst peice of a crap circuit I've ever seen.....
You have a good >80 watt dummy load?
Pump the 80 watts into that and see if the "feedback" is gone or if you can sniff where it's coming from. I'm thinking a good ground or shielding won't matter so much in this scenario (or Sinatra, as my spell checker thinks). The power amp should be shielded in any (metal) case.
wha-da-ya thinks?
