If so, I would guess that the difference in output impedance would be the biggest change with triode lowest, then UL and of course the highest output impedance in zero feedback would be pentode mode. Also, for the same amount of feedback(in dB), the UL should be(if properly designed) lower in distortion. With triode wiring, you may be able to use zero feedback but, power levels will be much lower.

No negative feedback.
For me, the extremely low parts count, made it an attractive DIY build.
Small chassis size (6" x 10" x 2" times 2) and budget limitations dictated small and inexpensive but good quality (Edcor USA) iron.

"No negative feedback."
What levels of distortion are you seeing? Have any commercial designs used UL alone, without other feeback?

Buy Chinese. Bury freedom.
I am not sure?
My old dumpster-found 1960's Tektronik O-scope, gave up the ghost a few years back.
I actually found the schematic (originally using 6V6 and 12AT7 tubes with a UX-80 tube rectifier) on THIS FORUM, dated March 2001.
As far as any commercial designs, I have NO idea??
