Started this months ago, but recently made some progress. The boards are done, and I roughed out the case today. Still need beau coupe work to make it pretty, but all in time. Hopefully, in a couple of weeks I'll have it running. I'm going to build two; one for each 2235 sub. The boards are designed and copy righted by Anthony Holton (Aussie Amps). It's 220W RMS at 8 ohms per channel. Don't know what the wattage is bridged, but it will be a scarry number!

NiceIf current capability isn't a limitation, that would make for nearly
900w into 8 ohms. Gonna need one heck of a PS to keep up with that.

Grumpy, the power supply is an Avel 625VA (2 - 50VAC secondaries) toroidal tranny with 40,000uf per rail. I'm building a surge board that will slow start the amp. This will keep it from tripping the house circuit breaker.
Don
running the secondaries in parallel? (guess I can look up Aussie Amps)

The PSU is symmetrical with +/- 50V rails.

Hi Don,
Sounds like that will get you maybe 140W at 8 ohms, unbridged, if I understand correctly that your DC rail voltages will be +/- 50V ==> (<35Vrms**2)/8. 10V higher rails would
bump you up closer to 220W (if my coffee deprived brain is working this morning)
Cool project, regardless.
