FOR SALE: Test Adapters by CBS Hytron and GC Electronics. These are three TUBE test socket adapters made for troubleshooting electronic equipment. The first two are for 9-pin and 7-pin tubes and they extend the tube socket so that probes may be attached to the side for measuring voltages or attaching an oscilloscope etc. to each pin. One each for 7-pin miniature and 9-pin miniature tube sockets. The third adapter is for testing NUVISTOR tubes in older type tube testers. It provides a 5-pin nuvistor socket oin top and has an OCTAL type plug on the bottom. GC Part number 36-532.
For the three test adapters, I would like $15.00 plus shipping.
