Hi Mike, the Citation V clone amp uses OPTs from a Sherwood S8000, at 7Kohm. Not huge transformers but very sweet. I built the amp for 6L6GB and 6P3S-E and it was great but decided to try KT66, and though it is run mildly (385V plates, about 42mA on each tube, adjustable) it has real punch and great sound. Susan Tedeschi and her Blues band - Wow!I used the original specs for FB; probably not correct for the new modified set up but it works: 10K resistor and 100pf cap. Without FB the amp barely functioned, sounded terrible.
I have other amps that you can remove fb and and I hear no difference, (but would obviously measure differently).Pete
