Thanks Darryl! Just how tight are those connections likely to be? I would imagine that there's going to be a fair bit of oxidation happening there. Is Deoxit of any value here to try and loosen the connections?

The socket should pull off easily. Just make sure to hold the crt base as you pull the socket so you don't stress the leads if the base is loose. As Chuck mentioned the biggest issue is with the HV lead. These tend to be very tight on their own, and can be corroded making things worse. If the button is stuck to the HV socket, you run the risk of breaking the lead off in the crt, or at the worst, cracking the glass in that area and ruining the tube. I have had these anywhere from very loose to extremely tight. It shouldn't scare you off, just be as careful as possible when removing that lead.

The 12AP4 uses an early 6 pin base with no key, just two large pins and four small ones. The filament is on pins 1 and 6 which are the large pins.

Thanks again Darryl! That's what I needed to know.

I have a collector friend who has noticed a syndrome over the years: he used to post notices on the bulletin board at work that he collects old radios and phonographs. Often someone would contact him with "some old thing" that they'd be glad to give him to get it out of the house.

But, he says, on any number of occasions after he's gotten them thinking about it, they'd seem to decide that if someone was interested in it, it must be a good collectible. And then the offer was withdrawn.

So strike while the iron is hot!

P.S. If you get the set, you really should consider keeping it. You'd be an instant "high end" TV collector. And it's a lot of fun.
