We are Located in North Carolina

All service performed by Degreed Electrical Engineers with over 46 years of experience designing and servicing Tube and Solid State equipment and Tube Testers.

The protection used in most all older tube testers is not enough to provide destruction when failing to test for shorts before doing a Gm Test. For example the line fuse bulbs and resistors will NOT protect your transformer and other components from destruction.

Here we offer a fully installed over-current, self resetting protection package covering:

Screen Supply

AC/DC Grid Supply

Plate Supply

Filament Supply

Main Meter

We receive many testers with bad transformers, meters and/or components. It doesn't have to be that way.

Buy this package installation and have piece of mind.

You can purchase our calibration service and this at the same time and have it all done at once.
