I also want to make sure that I am checking the right places. Terminals 1-10 are on the power transformer correct? If so terminal 3 and 8 don't exist. Other terminals are as labled originally in the manual correct? When I get home I will post some pictures. I was resoldering and melted my power switch so I have some more of those coming.

No resistance checks are made on the power transformer.  T1-T10 are the terminals on the 5 lug strip.

Feel free to repost your measurements.

ahh I pulled off my tape with those labels like an idiot. All seems to check out other than terminal 13 slowly dropping from over 300k rather than climbing to 270k. All other numbers check out.

You can proceed to voltage checks.

Everything checks out. Some that the manual says should be 100 are 107, but I am assuming that has to do with variances in caps and tubes. Nothing seemed more than 15% off so I plugged it up last night and it sounds great. Thanks for the help and amazingly quick responses! After getting to know her a bit I plan to install the speedball.

This project was so much fun I want to make a stereomour now for my speaker setup!
