Try it. Meter set to ohms, one probe at each end of the cap. (the cap that goes to pin3 of the 12AX7)

Do you mean you measure 0 ohms across that cap (one probe at each end of cap)?

On the 12ax7, I read zero. I set the multimeter to the ohm logo and put the black to the chassis and the red on pin 3. Read zero. I put it on the cap that the white wire goes to and it tired zero. The resistor that is attached to that cap is verified. It works.

What resistance do you measure with one probe on pin3 and one probe to chassis?

Pins one and three look good, so do their solders and resistors. Pin 4 and 5 is hooked up right. Slightly sloppy but no concern. The back of the board may be flawed. Easy to get turned around with it being mirrored from the schematic. I'll check now.

I'm Seeing the #1 post for the 12AX7 is really high. The rest look normal.

Found I had a cold Solder on one of the posts for the fuse holder. Fixed now. VERY quiet guitar through the speaker (Success) and very very distorted. Input?
