Well. Made some progress tonight on it. It had a couple bumble bee capacitors in it, I went ahead and deleted them with Orange Drops, and it had a couple others that looked questionable to I changed them too.
Still a couple unusual value bumble bee capacitors living on the convergence adjustment panel but those are easy as pie to replace. Just remove the back and there they are!
I ended up having to do the A/V mod. I poked and prodded the tuner section for a couple hours today, and I can't get it to adjust at all, or work remotely well. Seems to be a zenith sickness.
I'm gonna change the electrolytic capacitors next and go from there.
