I've got the nearly identical 37-670 and it's my treasure. Not the most desirable radio for cabinet design but a spectacular performer. It's my regular use radio and has been used in many DX contests. With eleven tubes and a packed RF stage it can be rough at times to repair. Learning how to remove the RF assembly, pull out the band switch shaft, and RF section assemblies will help tremendously- and it's quite easy.
