EICO 625 Tube Tester

Tubes Asylum

Questions about tubes and gear that glows. FAQ

I just picked up one of these tube testers. The tube roll chart currently does not work, but the rest of the machine looks intact and in good condition. I think it will test 7591A tubes (it has a socket that fits them perfectly) but I cannot find a guide for the control settings for the 7591.
If someone could tell me how to set the controls to test 7591As, I would be most appreciative.
Thanks.
Gary
