my first build. It works beautifully, here are pics! C&C

Somehow this post got past me. That is some incredible work. So this is you first build? Very nice indeed. I was following your progress, but missed the unveil.

Did you get the PI figured out yet? Definitely set it up so you're measuring AC.

I didn't know I had to give it time. I'll try again. I now set it by ear.

Thanks! Well no matter where I put the PI trimmer, I never get more than 1 DC volt mismatch on the PI.

This I cant understand. Maybe you dont wait enough. After every setting you have to give it time to set. After 5-10 second you should see effect. But more than 1 VDC.
I have there a matched e83cc. and 120/110k on plates. So you (me) are in any case mismached. I have there a trimmer with a spiral so you need 20-30 turns from one side to the other. I started in the mid pos. (5k/5k) and turned in direktion of feedback side. So the feedback side will get more volts than the other (as schematic wants). I´m noe at around 7VDC different and it started that every tone wants to feed back. Here I stoped.
This story is to be continued .
But what I wanted say is: with the 10k trim you should see a lot more than 1 vDC different.

BTW for first build ... wow.
Not my last will look like yours.

Thank you very much. Yes this is my first build of anything really.

I am waiting on a friend of mine to get his scope. That'll make things easier

That's cool. Even though a scope isn't needed it's nice to be able to see it visually.
