Aleph 30 is slightly simpler. What speaker are you going to
drive? |

regulated supply
I ask to you Nelson, it's possible to adapte regulated-modulated pwr supply from zenv3 for aleph30?
And use a single power MOSFet like irf040?

I've built both of those amps, and while I had no problem with Aleph not using any PCBs, I wouldn't probably approach A-75 without those. While output stage is not a problem to wire, the front end is a bit more complicated.
That said, Aleph is also a better sounding amp.

Actually I've built Aleph 5, which from construction POV is not that much different than Aleph 30.
