I decided to take a break from the HV troubles in my RCA 6T65 and take a look in the radio unit in this again. Partially because I never cleaned the controls in the radio unit I swapped in there from the other set, and you have to shake the volume control to get sound out of both speakers, so I decided I was going to take a go at fixing the original unit, and if I couldn't get it going I was going to at least clean the controls in the replacement.
I fixed the old unit, and I'm happy I chose to make some voltage checks before just going and replacing that "integrated circuit" thing that looked bad, it turned out the problem was just caused by shorts in the 1st IF tube, an easy fix. I also turned up a few resistors which had drifted slightly off of tolerence, it works as it is, but I'll swap those out before I put the unit back.
