Aleph testing

[hifinerd]

Hello all,

I am hoping to test my new Aleph 3 boards before I assemble the final amplifier and go to the effort of matching fets. I was contemplating assembling a board with only a single pair of output fets rather than the usual 4.

As far as I can tell the circuit will work ok with a single pair of output fets without modification. Is this correct or am I going to fry something?

Your advice is appreciated.

Greg.

There's the mini-Aleph (AKA mini-A)that uses one pair of (unmatched) IRF240's per channel. It's almost identical to the Aleph 3.

Keep the sense/source resistor number ratio the same and you should be good to go.
