Good day,
I have this rebel 20 which I bought online from a used store in Japan. I was aware of the buggy issue which I thought was only a leaking filter cap. I have a jcm2000 that sounded like this and fix it with a recap job.
Well Ive changed most of the filter caps in this egnater, next to the power transformer and even swapped out the resistors, but the weird ring mod tones are still there.
Here's what it sounds like

There's also this low hz hum. I checked the grounding of the filter caps and they were ok.
Also Ive tried using the preamp section by sending it out on the return of my classic30. Awesome tones.. but I wish I could make the egnater's power section work by itself

I havent checked on the bridge rectifier going to the filaments since the preamp is working just fine.
I thought of checking the big resistors near the power tubes next, but posted here instead since it might be futile. Is the power transformer busted? What else could be the culprit for this ring mod sound? Or is this what they call wolf tones? Thanks!
Schematic i got is from elektro tanya
