Does the line voltage droop when you transmit, causing a drop in filament
voltage?
Do you have ceramic capacitors in the tank circuit that heat up and detune the
tank?

Anyone have an idea why the power output of my dual parallel 833C 160m amp
often drops 200+ watts after several seconds? Re-tuning does not bring it
back up to the initial output.
Not that a drop from 1500 to 1300 watts is a big deal, but inquiring minds
want to know the reason. :-)
