You have an octal socket and a lead for a grid cap, which means your set falls under a production change in which the 7J7 was replaced with a 6J8G. The 6J8G has an octal base, requiring an octal socket. The pinout of the 6J8G is different from the 7J7, but the two tubes are electrically identical.

So don't go crimping those tube pin contacts...a loctal tube won't fit here.
