Thank you fellas.... It sounds like I should go through the exercise of changing the electrolytics or maybe invest in an ESR meter at least. I have a scope but I'm not ashamed to admit I'm completely illiterate in using it. I did remove the diodes from the circuit before testing, but as far as I know, they work by allowing current one way and not the other and this simple test tells me that they are okay. Possibly I should look more closely at these Doug??? The picture does not start to slip, like if a tube was gassy or weak. It just goes haywire like the HH is just plain off. Like I said, I can lock in the HH after the set is warm, but it will go out of sync as soon as I change the channel or fool with the AFC. I do have freeze spray and will shoot the caps in the HH section, but shouldn't I be more concerned with the electrolytics at this point as Chad suggested? What tubes are in the four tube model??? From my Sams, it looks like these sets all had the same topology for their run.
Generally, I go through the exercise of changing all of the electrolytics completely out, but in a set so recent, I just brought it up slow although I admit that I have no idea what the issues were before I got the set. It's a curbside find, so to speak. I was hoping that I could get away more easily than that
THANK YOU ALL AGAIN! I'll post what's what as soon as I can get back to the bench.
