I picked up this VTVM about a year ago and finally got around to taking a closer look.
The pointer was off a bit so I've removed the button over the meter zeroing control. A little tweaking took care of that.
I'll try some Novus on that scratched faceplate.
Very solid cast aluminum case. Perhaps an old D cell leaked into that corner ?
If it did leak, it couldn't have been too bad. Looks like the previous owner replaced the battery recently.
The parts list calls for a selenium rectifier, but that looks like an early silicon one to me.
It's all built on a thick PC board.
I tested a few of the precision resistors and there all within spec
Every capacitor (even the 0.1 uF) is ceramic so I'll leave them alone.
I'm going to replace that 10 uF electrolytic, test the D cell and go through the calibration procedure.
