Thanks guys! Tom, I was thinking about that DVD-have heard it referenced once or twice. I need to pick one up. My Sencore Color King does okay but some sets (including this one) just don't like it. I can't get a dot pattern to lock in. The next time I tear into this I think I'll swap out the low value caps on the AGC board and also do some good probing of the color circuit. John, good tip about those micas, I'll have to write that down. I swapped the HO tube with another without any change, but then the other one (though it looks like new) isn't NOS. I would just go and buy one but this summer I bought a truckload of tubes, all sitting up in the attic now. There is a good chance that I have one NOS in that pile, and I will try another swap. The worst damage I might have done was once, during this process, forgetting to put the horiz osc tube back in the socket. I then stood there with a dumb look on my face trying to figure out why the HO current was pegging the needle!
