Vintage Supreme Instruments Corp Vacuum Tube Voltmeter Model 565

Description

Here we have a Vintage Supreme Instruments Corp Vacuum-Tube Voltmeter Tester Model 565. This was my Father's, who was a repair man and it was part of his tools he carried with him in his service call van. I have not tested this unit except for plugging it in and zero adjusting the gauge as I am not proficient in using such a device. Since he used it on a regular basis I assume it works properly, but again do not have the experience with this type of device to properly test. It is in superb condition considering its age and appears to be complete with all accessories. Sold as shown - untested.
