That is the 2nd time I have heard of "Thermoforming". The first time was with the socket assembly of my GE RCA Radiola II. The stuff appears to be able to distort under normal to slightly high (attic?) temperatures, as many of these socket assemblies in the Radiola II are warped. and collectors actually recommend removng or "unlocking" the tubes. (Mine is fairly straight.)
