26KC20 Tuner drifting issue.
Hi all, I've been watching the black metal '63 Zenith since I finished the restoration. The last two days the tuner has been drifting all over. I checked all the RF/IF tubes and the 6EA8 in the tuner was shorted, the 6GK5 was burned up with no emissions by that point. I replaced them and the problem is still there but not as bad
 . But now it has drifted out altogether to a black screen, came back with herringbone lines and now can be tuned in clearly but has no color. If you tune in color it will be very fuzzy. Tuners are not at all my specialty, does anyone know where to go from here. I have pics if that helps. Thanks.
