I recently built a 160-meter only amplifier using a pair of GI-7bT tubes. It
was easy to make a socket for them starting with one
of the $2.99 aluminum mini-boxes that are sold at Radio Shack. The
cathode/heater ring connections used stainless steel hose clamps
and the small heater connection used plate caps of the size for 6146 tubes.
There are photos of this socket in the thread at

I don't know if the base is the same as the GI-7B but it might be. Check the
sizes and if they are, there is a guy who makes sockets
for them on e-bay. You can mount them without sockets but they do need air for
axial cooling...unless you change the cooler to one
that works with transverse cooling.
