Electronic Development Corp, EDC, MV105G voltage calibrator, standard (#1G)

Description

EDC MODEL MV-105G VOLTAGE STANDARD ( CALIBRATOR )
I am listing as 'for parts not working' for the simple reason I cannot guarantee accuracy , stability or how long it will work.
It has been functioning for me for about 15 years. I acquired several MV106 and others about the same time.
All have worked fine with a little TLC.
My use has been off and on. My intent was to upgrade amps and references of  EDC and K-H standards, old style.
This unit comes with one of my new amps. The circuitry for the galvo was not changed.
My measurements of output were done with an uncalibrated, but very stable, HP 3456A DVM ( 2 additional 3456A's  for comparison).
Also I have 3 GELLER voltage standards to use as another check. Two are 1.018V and one 10.000V. They are within 10 PPM of an original calibration my son did about 8 or 10 years ago.
Take a look at the pictures to help make up your mind. If you need more pics I will supply them.
Any questions are gladly accepted and answered quickly. I don't blow smoke.
Please do not buy if you cannot accept this minimal risk. Remember these critters are fairly old, like me.
If you win the auction you can WAIT FOR MY INVOICE or ask for an invoice. If you are closer to me and the shipping charges are lower than I have listed then I will lower it in the invoice . If the charges are more than I have in the auction then you will pay only what the listing says. Shipping can go down but not up.
Thanks for looking...
