Hi Mark
It is a great tube. And, you don’t need a socket - Alek and I cut out a hole in 
the chassis and I used 3 little L brackets to hold the grid ring hard onto the 
chassis. Then, a couple of stainless radiator clamps around the Fil and 
Fil/Cathode rings under the chassis for filament and input matching circuit 
connections. Works great.
Best 73,
John VK6JX
