Thanks for the tip! I’ll check it out

Sometimes it’s good to procrastinate, I would have never heard this tip

Hmm, besides an old indiegogo site I can’t seem to find these PCBs

@uncola - the Folsom guy says I can still buy PCBs. Is it one amp PCB for two channels? I can probably make a pretty compact amp if that’s the case. Especially since it’s single supply instead of bipolar.

Yes it's one amp pcb for two channels, then the power supply pcb is called the antipole. I can't recommend it enough, it's astounding how good it is and that's not just new toy syndrome talking :)

here's a picture gallery of mine, I have the BoM suggested optional jantzen superior-z 1.5uf input caps in mine, I think they are $18 each at parts express. supposed to make the soundstage big and it definitely did for mine https://imgur.com/a/dJBes

I bought the boards! I think I’ll do a separate power supply so the amp can stay compact on my desk.

Also noticed the amp is regulated from a single supply. I think I’ll put off building the linear supply and use an SMPS power brick. Hopefully the regulator does a pretty good job of the switching noise coming from the SMPS.
