Sometimes the flake tube would work in a different device with operating volts . They are valued by collectors and those in music radio fields working with tubes. It is in good electrical condition and fully working except for a worn ac power plug.

These special tube testers, called grid circuit were very good at finding bad tubes in RF and if plus high gain audio circuits. Gct-8 grid circuit tube tester. I will include a new plug. Being too close to the cathode or for other reasons, grid would emit electrons creating noise.

After testing the unit I cut plug off for safety yours. Most testers were not sensitive enough to indicate these problems. Sometimes a regular tester would pass tube with good dc gain and emission, but it still make weak noises due to poor grid condition. Sold as an adjunct to their regular model's, it uses a dual tried 12au7 drive magic eye tube detect small grid leakage that most other testers couldn't see.

After checking tubes on regular testers which test for the major condition of a tube basic quality tests, gct8 will find that tried 12ax7, etc.
