Update 13-1-2012, So I took your advise James and tool a few days off, When I got back on it I decided to check resistance on the rest of the tubes in the video section. I found two resistors that were more than 50% out of spec and replaced them, fired up the set and with a few control adjustments had a good picture,. I've been watching the Burns and Allen show for nearly an hour now and it seems to be stable at this point. I'll run it for the rest of the day and if it's still good in the morning then I'll but it back in the cabinet.
Again thanks to everyone for your advice. James I appreciate your interest in this problem.
I have to say I'd rather bring a TV back to life that hasn't worked in 40 years then to try and fix one with rodent damage.
