This is a great read. Not so useful for guitarists, perhaps, but it's good to be familiar with this info.

MPS Iron
I got a Musical Power Supplies OT40PP for the Rocket build. I have one of MPS's earlier offshore versions of this OT in Bodie and it works well in that amp.
This new model is made in the US with M6 steel, 4/8/16 ohm taps on the secondary, and 4k2 and 3k3 primaries.
It's a great chunk of iron at a great price. No idea who's doing the winding, but this guy knows how to spec his iron. I'm super happy, especially compared to the stock Crate iron.
It's kind of odd to think how similar the Fender 5F6A, Marshall JTM45 & Plexi, Vox AC30 (Trainwreck Rocket), and Sunn Model T are. Okay, the first two really aren't much of a surprise, and there are countless other examples... I guess it's just a really popular topography.
I can kind of see it, but it's just not doing much for me. Maybe with a different tone stack or some NFB. Just a little more midrange and a little less bass would go a long way.
