Zenith tube sockets: is there a trick to re-mounting them?

[Tim Tress]

To solder those tube sockets, and the ground connections, you need a BIG soldering gun like a Weller D550. The smaller ones just don't get the joint hot enough. 40 years ago, when I was working for a Zenith dealer, we stocked the little grommets and plastic rivets that were used on a couple of the tube sockets; they were getting brittle and breaking, even back then.
