IIRC, Shea from Monomyth loves modding these so the xformers are probably fine.
Thanks for the feedback.
I've been messing around with a 1987xl that I had modded into a Jose / Cali / CCV sorta thing.
It sounded pretty good, but not as good as some of my other amps, so I set it aside and focused on other stuff.
I recently decided to have another go at it, but I've always wondered if the amp was limited by the re-issue iron.
Anyway, I've been focusing on adjusting the negative feedback / presence / depth area, and I think I've finally got it sounding really really good.
A couple of guys on here have said that the secret with diode clipping Jose style amps is in the NFB, and I think they are correct.
The other thing I've done is stiffen up the power supply and raised the pre amp voltages to compensate for the compression from the MPSA06 diodes. I love the tone of those things, but they don't have a very high forward voltage and they clip like a MOFO.
There doesn't appear to be anything wrong with the output transformer at all.
I think the problem has been solved.
