Hi everyone,
New toys arrived ...
A LM399H Voltage Reference, to check my two HP3456A. Preliminary test are promising on the twenty year old calibration of the two meters. I did also include pics from my custom un-calibrated one (using LM399AH).
A beautiful HP 5326B with eight nixies (Opt 001), from Max K., this is the one spotted on his video BEB #125 .
A Goerz-Metrawatt SE460 recorder, it seemed smaller on ePay than when it was delivered... If ever anybody have schematics or service manual for it, feel free to share it, I did not find it :(
