To Chimes, I'm not sure how much voltage the megohmmeter puts out either. The guy that loaned it to me said something about 4 times the operating voltage. He could have meant that the meter puts out 4x or that is what I needed. There were three ranges, 200v, 600v, and 1000v. I used the 200v. I seriously doubt that the momentary spike would damage anything. Nothing got hot. Also thanks for the link! Everyone should be able to use that info. I find the color coding confusing as my transformer does not seem to follow suit with what they show.

To Bill, no I don't have the items you mentioned. However I feel like simple resistance readings should tell the tale of a major short like I have. I should not have resistance readings from disconnected wires to ground in places I am getting them. A few minutes ago I took some readings. Here are some examples. These checks are to ground. Pin 4/5U4=1,300 ohms, pin 6=1294 ohms, the lead that goes to the switch has 91,000 ohms. I get 1.8 ohms across the ac line with the filters disconnected. Thanks Bill!!

To Bryan, I kind of knew round was better but I wasnt sure about size. I know any of us would like to have one of those huge DuMont Royal Sovereign sets with some ridiculously large crt, so I guess size is not necessarily a rule of thumb. Also I have a couple of the 50s rectangulars that I know are good finds. I always thought that interest started falling off around the early 60s with old TVs. The early Color sets then take over. There really are no guidelines as the hobby has expanded somewhat and there are some who find 70's stuff interesting. Some of this is relative to a persons age if you think about it. One day someone may find nostalgia in the plastic junk Walmart calls TV's. Go figure!!

Thanks for the help everyone. Still open to ideas and suggestions....
