This did nothing but allow the amp to pass type-acceptance from the FCC. Dipping and peaking went out years ago with class C! You are showing your age! You shouldn't be fooling around with tune and

I didn't, Rich, until 200-400 watt transceivers started hitting the market. My 3CX3000A7 and your 8171 would not be affected, but 400 watts into some of the popular smaller tubes might not be pruden
