 Thank you for viewing this Sterling Vacuum Tube tester. I do not have a lot of experience with Tube Testers. I now this one worked. The two small gage type with external probes are completely foreign to me but I am not an expert by any manner. The one pictured on the right side has a broken wire. I think it is an easy fix but I thought it would be better for someone who knows more about them to fix.  I guarantee the two to work or I will pay the postage to return them and refund 100 % of the purchase price.
The testers are antique and in good condition except for one of the round gage type, has a wire disconnected. I think it is an easy fix but want to leave it for the buyer who may have more experience.
