For a shunt-fed small *guitar* amp, is there any compelling reason to
justify the high cost of a parafeed-designed OPT over a plain-Jane
guitar amp OPT run with almost no DC (i.e. "almost" meaning a couple ma
shunted across the cap through it to help keep it stable)?

I haven't fooled with one & ISTM that for 80-7Khz & where some
distortion is a desireable norm, one might use an ordinary smoothing
choke of decent quality with a normal OPT & still reap most of the
benefits over the traditional config in the 10w category.

I'd say build it out and see. Parafeed is bull**** IMO but for a
guitar amp where you want that distortion give it a try and see.

Think of it as a Heising modulation stage running AM carrier with the
modulator disconnected. :-)

With 2 other in-progress builds, a production proto running behind &
repairs coming in the door, I don't want to dub with an experimental
low-end parafeed build until I have some experienced input that may
justify it.

The regular guitar OT will work. Since there should be no DC, I've also
used distribution transformers in this application. They are usually
quite cheap.
