Default Feeler: F/S Chipamp.com/Pass Aleph Mini A

A few specifics:
1. chipamp.com amp boards
2. Peter Daniel PSU board (I think there is 4X33,000uF caps in there now)
3. Hifi2000 2U case with heatsinks-black front 4mm panel.
4. Either IRFP244 or IRFP140 MOSFETS (I think I last had the 140's in there)
5. Antek 12V 200VA xformer
6. Running ~0.33R source resistors now

Sinks run warm - not hot. Amp is quiet and "balanced".

A few noteworthy issues...the bottom of the chassis has a few extra holes in it from swapping out the original chipamp psu board. I replaced a couple zener's on one of the channels and an IRFP610 on the same board. One of the pads came loose on one of the IRFP610 legs but there are no connectivity issues.

Below is a pic of an early state of the amp. The wiring was tidied up a bit and shown is the old chipamp PSU board...not the one that is in there now.

If there is interest I will post or PM updated pics, actual values and measurements as requested.

I would like to get $200 plus shipping
