Repair Service and Calibration
These services are for repairing and calibrating tube testers to good working order. This includes several services such as basic tube tester repair, calibration, refurbishment and restorations.
The upgrade features I provide are for improving the performance of older tube testers. To allow for more accurate test results, reliability, and for providing improved features to allow the user to perform additional tests not available on his model at the time.
Parts and Bogey Tubes
Several parts are available for sale to replace bad or broken parts as well as improving the general quality of your tester. This includes many new meters, reference Bogey tubes, lamps, and other parts.
