Need help - unknown first watt?!?

[noamgeller]

Need help identifying this monoamps!
If it can be done, this is the place... I only know they are first watt inspired and are delivering 60watt per amp. By the way, they are for sale 🙂

Aleph, some , no doubt

only these are having 3pcs of TO220 mosfets on pcb

external/daughter OS pcbs

Agreed. They look like one of the old BrianGT boards.

Thanks guys appreciate your help!

+1 for the BrianGT boards ... have built my "Aleph J Single" on those boards ... 🙂

So I would guess Aleph 3 / Aleph 30 front-end with higher output power via 3 pairs of MOSFETs in output.

Photo shows my original Aleph Mini before conversion to Aleph J. Instead of the daughter boards as in noamgeller's version, mine got one pair of IRFP140s directly soldered to the board.
