Esentially nothing. 0.007v, jumps to 0.021v, then back to 0.007
Using ground as reference each side seperately has -9.67 vdc

Found the noise. U4 was defective with 9vdc on every pin. The amp produces audio now. Gotta replace the group of FET's associated with Q104 and then test thouroughly.
Still cant get the protect LED to light.

It didnt show a short measuring in circuit, I swapped it out and now the LED lights as it should and the horrible on/off pop went away as well.
I'll get the FET's changed out, test, and update this post for others.
Thank you as always for all your help.

If they're properly soldered to the MEHSA strips, they should be about as good as the originals. The problem is... A lot of people don't get them soldered down with 100% coverage.
Side note... The transistor wasn't shorted. It was open, that's why you didn't read a short when testing it.
