I posted high res pictures here and would appreciate it if you could take a quick look. Let me know if you need more detailed shots of certain sections.
Based on the way that your power trafo is wired, specifically that it has the exact same color coding and layout of the wiring, I'd guess that your amp uses the same Hammond transformer.
And as much as is possible I'd appreciate it if folks would discuss Mikhail and his business practices in other threads. This thread, like the two others like it (for now?) is meant as a way for owners to identify serious issues with their amps. I once saw Mikhail bring 10 or more Extremes to a NY regional meet so unfortunately there could be a lot of these out there.
