Funny thing about output transformers is they have to match up with the output tubes being used. Mine is a single ended output using a 50l6gt.
I think this would work a charm... but $80 is killing me.

he did say 60 or 120 hum but not sure if that helps with this scenario
120hz is what I'm dealing with. My suspects I mentioned are likely 60hz issues, so I think I can safely eliminate tube heaters and switch as sources.
I may have to just suck it up and be ok with some extra buzzzzz.
he might of said buzz/& about ground'n out to check for source if i'm rem. correctly _close enuf i hope 2 help
It sounds like there is a tip in here for me... I'd love a clearer explanation of how he would check for the source.
I use the term buzz in reference to 120hz. Hum = 60hz.
gotcha
Ok. Last word on the subject for now (ty for entertaining me):
I found that the ground for the tone knob is on an eyelet that connects directly to the chassis. I have also run a ground wire from this eyelet to the preamp ground section (which includes grounds for the input, 1st tube and volume knob).
I probably created a ground loop this way. I will remove the grounds from this eyelet so the tone knob is only grounded alongside the rest of the preamp section and report back later when I have time... 🤞
I was suspecting the tone knobs ground already because with no input signal, the buzz strengthens when the tone knob is adjusted.
Oddly, the buzz disappears when the tone is all the way up and strengthens when reducing the tone downward.
I'm excited to have a lead to investigate. Ty again for your support.
soundz feasible/let me know
Embarrassing to admit... My tone circuit was configured incorrectly. Oof. The potentiometer wasn't properly grounded. Super lame.
I did fix the othrt potential ground issue I mentioned before.
Works a charm now. Buzz free.

It was super cool of you to let me talk through it. It helped focus on a plan of attack.
Tell your friend I said thank you as well.
