+1 - I don't have that chassis, the sams doesn't normally show the socket, so I'm blind without a picture, but have over 200 tube sockets. 3A3, 3DB3, 3AT2, what is the rectifier?

That socket assembly in the pictue looks like the all plastic type that I have heard about. I count 12 pins; same as my 3AT2. That picture is teasing me! I sent a PM, but I'm not sure if you got it. Not rushing, just anxious to get this thing going again.

I never saw a pic of what you needed - did you ever post a picture? I don't have the chassis, so a pic would be needed. If it is what I think it is, with a compactron socket riveted to the corona can, a Zenith 78-1863 is the part number, IIRC. The can with socket fits into the HV cup, and comes with the flyback. I've never replaced one - most of the arcing that ate HV cups was from a dirty cup or too much HV. The cups I have replaced - mostly ones that arced near the cage, else we cleaned them and put a glop of RTV3145 (yes the acetic acid kind) on the hole.
The pins in the socket (except the one or two that are soldered to the corona can) are replaceable with any pins from a compactron socket.
