john-china · 18th November 2004, 01:50 AM

i got a lot of irfp9240s and irf610s, so i want to use them to build aleph,
i call this aleph a reverse aleph. then, has the reverse aleph same quality as normal aleph.? has anyone built this one? any comment and suggestion is welcome .

In theory, it's possible. No, I haven't done it. I've got so many Aleph variants sitting around that I trip over the confounded things.

I'm planning to do the same with Digi's zen headphone amp boards. Just reverse the polarity to the supplies and also all polarized caps and change the NPN bipolars for a suitable PNP and reverse the Zener in the front end current source. Did I forget anything? It's still a non inverting amp, so speakers polarity should remain and input(s) remain.
