Yes I think you are right about the disassembly.

If the people who made the 211 amps in this thread are around and see this thread...

then pop me a line.

Because you are beyond belief awesome in your understanding of how to make amps that sound completely phenomenal.

No exaggeration. They just do.

Absolutely outstanding effort.

Hopes of a response? Close to zero. But hey. Some people deserve serious credit and never get it.

Version 2 of the Michell AC power supply will appear maybe within the next two months.

I won't rush to publish the errors that were made in version 1.

But this is seeming to be a great solution. Maybe. Possibly. Or not.

I reckon, though.

Version 1 worked for a while and then broke. I had tied both negative terminals off the TPA3255 card together and connected it to the earth out in the mini-XLR as advised by I think Grok at the time.

Fine for single ended output but not for BTL, which is what the TPA3255 uses to increase its output.

Basically the earth wire went O/C on the mini-XLR and the TPA3255 can no longer achieve full output.

Ordered a new card.

Looks like nobody built it anyway. Which is pretty sensible given I said I didn't know what I was doing.
