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.
