Welcome aboard Allribbon !!!
Everything looks really good for first time board builder Im Impressed !!! :thumbsup:
I might have some of the BP caps for your driver board. I can send you them at no charge .
Well, I believe it's very helpful in deterring people not to go under the hood of these amps.
And I was considering having you test mine .
And his statement "Would amp be in protect if vfets were bad?" doesn't necessarily
mean his unit is in or out of protection , to me it was just a question...
I got that from your video on the K77's . Where you do the diode test to see that they are not at least fried. I think you said to see if they have a "pulse"
However having said that, the further testing you do with your quad power supply
testing is the proper way to go. :thumbsup:

Its in the thread I linked.
But first have you done any work to your B2 power supply and do you have the original filter caps still in the unit?
If so, Id first test the v-fet for and initial "Pulse" test I attached. if they pass the "pulse" test then Id rebuild the PS and get new filter caps.
I had the same issue . Replacing all transistors on the driver boards solved my issue.

Best sounding for me is a tough one, but to be a bit different my original pressing of "Head on the door" by the Cure .
Favorite is also tough
Maybe Son Volt's "Trace" Album.
Or Dexter Gordons, "Dexter rides again"
