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.
