Hmm okay.

First thing that is apparent from the photo of the tops of the tubes.

Each vacuum tube must have its own parasitic suppressor.

That is the resistor connected to the anode/plate of the tube.

Not enough photos of the bottom. But. If I remember correctly.

The plate choke of the driver tube hangs down from the top cap "Anode"

just like on the finals. If this is the tube turning RED. Then I was right on that score

in a previous post. AC or better RF. RF is actually AC. But at a much higher frequency.

I guess. The plate choke of the driver tube could be in the chassis ? Well tomorrow

will find one of mine. With a complete Un-Golden Screw Driver-ed specimen.

Perhaps yours can be made to function properly.

Best Four fingers & a Thumb !
