Your Plate wire is too close to grid wire near your powertubes. Try to move the wires..
..And then you can remove the grid stoppers..

Measure the DC voltage over the pot. If there is.. you have a leaking cap somewere

yes. I have SE-version prototype ..and working but with no extra gain stage. The cathode bias resistor is straight from the datasheet.. The feedback circuit is to manipulate the frequency response and amplitude of negative feedback. (More gain - more feedback at mud frequencys) ..I dont know if ther...

..Maybe Ill just do it like this and forget the extras

..and sorry about my bad english

..schema..

Im using negative feedback to EQ and want to put an extrastage next to it..

How do I connect one triode stage to create a Non Inverting Recovery Stage??
