Building the Audio Note Kit 1 SET amp...

Grannyring, Looks like the Wima DC Link caps I am trying in my power supply and the ClarityCap TC600 you are using are both Metallized Polypropylene. Looks like we are on the same path. Regards-Jet

Well, I re-soldered all the joints between the valve base tabs and the pads on the Driver Board PCB but whatever's going on wasn't fixed because I'm still getting a distorted signal on bass-heavy material on the amp.
Just got an email from Pete (Digital Pete) Fulton in Florida that my finished driver board is shipping 2-day post tomorrow. So, I should be up and running over the weekend! I hope by comparing the two boards to at least figure out what the problem is/was with my Driver Board!

Okay:
I received my new Driver PCB from Digital Pete in Florida, ANK's designated builder for prebuilt ANK kits. It arrived on Friday. As you'd expect, the workmanship is first-rate.
I've managed to remove my driver board from the amp and hope to get Pete's board installed completely by Monday. I'll report back when I do.

I am really anxious to hear about your results Rebbi. God Luck!

Roxy,

I chuckled at the likely typo "God luck"--if it was my soldering skills involved vs those of Rebbi's, I'm quite certain the divine assistance would be most necessary 😄!

I too am anxious to learn if the new board solves the issues with the amp, and pass on my best wishes to Rebbi for success as well.
