What you describe, above volume 8 on sustained chords clearly sounds like feedback through the tubes, chassis vibration coming back through the tubes, etc. Could be a bunch of things.

Once he swaps tubes I guess we'll get a better idea.

I'll reinsert the old phase inverter and trem tube and find out for sure. Honestly I just felt like playing once I heard the ugly distortion had gone. Thanks guys!

I was simply tired of doing one tube at a time and didn't think the trem tube would make a difference because several different tubes had already been in there while the problem was occurring. I had never changed the phase inverter until yesterday, mainly because it's a JAN blackplate. So I'm quite certain that was the one. But you never know.

This place is a cornucopia of in-depth technical knowledge. The best-of-the-best techs, designers, and engineers in the world unselfishly offer their assistance on this site, and I think we owe it to the next guy to clearly show the resolutions in our threads, including info on hard to find parts and non-conventional problem solving. In the end, it saves bandwidth and many times keeps the pros here from answering the same questions multiple times.
So yes, please do swap those tubes back in there (hope you know which one went where ) so you can put a lid on this one.

But I had been watching this thread pretty closely and watched as each issue got sorted out and its root cause identified. I'm a novice, so I pay attention to these threads and learn what I can from them, which many times keeps me from having to start a thread of my own. For every thread I've started here on MEF, I have easily solved dozens more issues on my own by searching for previous instances of the same problem I was having.

I'm finally going to have time today to swap the tubes back in one at a time in order to find out for sure which was the problem and report back.
I've had maybe two or three hours to play it since I sorted the problem. Sounds really great. No noise problems or grounding issues. All settings work properly, the effects are flawless. I'll see if I can record a clip through my interface or phone.
Not sure if I posted pics of the tubes or transformers, but I'll go over that. PT is from Classictone. It's running 25-30v over schematic voltages. Maybe a mojotone would have produced a lower voltage but from the spec sheet, the classictone looked like it would. Choke and OT are mojotone.
V1: rca 7025
