So the part of the board that slides onto the pins of the tube. Can I check that in any way? I know this thing has some hours on it. Counter says 65000. And I just found out that left speaker was bad. Changed it out with another and is working now.

Not easily (pics?)
The problem is that many of these develop a green coating inside the socket assy that becomes resistive (not measurable) over time and humidity. Back when they were new, we'd order a new socket. When they got harder to find, I'd take them apart. They're usually held together with melted plastic posts. I would drill them out and carefully separate the front and back half. if there was green (or worse) tracking between the Focus pin and the ground pins (there's a built in arc-gap in there), I would get a Dremel and carefully grind out the contamination like a dentist would remove tooth decay. Clean with IPA and dry well. If it was repairable, I'd reassemble with a couple of well placed drops of RTV where the plastic posts were drilled out. John |

There's also a chance that the cover over the focus pin may be removable by unsnapping the little fingers that hold it together. If I can't find a socket, we'll try looking under the hood so to speak. John |

I found one that the focus input tower is cracked/broken. Probably still usable but you'll have to RTV the focus lead to stay in place.
I have a friend who has a storage area that he was cleaning out, he may still have a board I can grab a socket from. John |

John, that socket u sent me is bigger and won't fit.Also, does anyone know if these are supposed to be touching and is it OK if the board is alittle dark around them?

The dark is normal as long as it's not burned. There is high voltage on the socket and the static charge pulls in air borne particles like ciggy smoke. John |

Even if I used the whole board, it wouldn't fit the tubes pins.
