I know I checked the color stage tubes (because when I got it it would not produce color since most of those were weak or bad, and thus were replaced), and IIRC I swapped the vertical tubes as a quick cure attempt (before I set it aside), and I may have tested the horizontal tubes when working on it originally (IIRC the original hot was down to air, and the osc. tube was dead so those and possibly the HV rect. were changed...I think it had a no HV issue I fixed by tube replacement before I replaced the bad B+ doubler cap).....I went over the tuner, IF, and AGC trying to fix the tuner when we were working on a deal (those were fine).
Some of those memories have 1-3 years of college classes written over them in the full (make that overfilled) hard drive that is my mind,....So I'm not certain I'm recalling them right. If you don't have a tube tester I could bring mine over and we could test them all.
