gday all
still have the aleph 2 boards
complete and working ,all good parts used with tec diy matched semis
i will bundle them with 2 x nuvotem potted 500va25/25 trannys
for $300au the lot
these are very good trannys all you will need to have a working aleph 2 is power supplys
they are high bias so you will need conrad 151/350 sinks in mono blocks minimum but the sound is magnificent
the above is setup to run harder speaker loads hence the lower supply voltage/higher bias
i can supply the sinks for extra cost shipping to au only as the trannys are very large and heavy
still will consider swaps
forgot to add sorry 3g the f4,s are gone

Bob, can you please PM me with these details? This is going to be my next build - driven by a hotrod DCB1 in (undertermined) full-range drivers.

Buzz, I would still appreciate some details on this. I am about to build a BA3 (no feedback) to go with an F4. If there is a way to graft them together and bypass the front end on the F4 boards, I would be very appreciative!

Thanks,
Eric

Let me test a couple of options and Ill let you know. You can bypass the input on the F4 the BA FE without doing anything else other than connecting it in proper place. I am after dropping any coupling caps, through a balanced variation.
