Building the Audio Note Kit 1 SET amp...

Not sure it was a typo, considering Rebbi's profession ;-)

I will say a Mi Sheberakh prayer of healing for the amp tonight.

Hi, Guys,
Well, no joy yet. I replaced the driver board with the one that Pete sent me but it doesn't resolve the distortion issues. So I have packed up the amp and will ship it out to Pete in Florida tomorrow. He promises to get to the bottom of this.
I should mention that both Pete and Brian say they've never seen an amp behave this way. Usually it either works brilliantly or it fails miserably due to a build issue, as in "terrible noise in one channel," "really bad hum," "no sound at all" or "bursts into flames." This whole "sort of works" thing is just bizarre.
I'm sad not to have ironed this out on my own but it may just require someone with the required debugging expertise being able to get their hands on the amp in person. Pete should be that guy.
I'll update you when I know something.

Hi Reb,
Pete is just the nicest man around; really talented, and humble as well. I know he will do it for you.
As a sidebar, I have to say that on my efficient horn speakers, this amp is quieter than 3 other SS amps I tried. That was a really nice surprise, as we all know that noise obscures detail, as well as causing long term listener fatigue. When I stand with my ear to the drivers, it is really silent. Just a great amp.

I'm very curious to know what Pete discovers for this rare type of abnormality. It will be educational.
