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.
