Talking about paper amplifiers........
One phenomenon I've observed is when the paper amp
turns into metal and other bits, and how when the bits
go into a box with a cover, the bits behave differently with
the top screwed on so I can't look at them misbehaving.
Case in point: High Voltage RF Chokes that calculate
one way, measure another way on the bench and then
let the white smoke out when they're installed in the amp's
RF Chamber with all the covers on.

I don't know, of course. And as the thing is now in the process of change,
I'll never know what it was. Once the change process is complete, I will
measure the reverse isolation on all bands.

But you can hold them down with nichrome weights! -:)
