A Simpson 715 AC VTVM Part 6: Intermission

When we left this project in February, the unit was working but the selenium rectifier quit before I could do much with it. I believe I had enough data to make an educated guess about what size resistor is needed to replace it. Seeing as how the SICo 76 is done, it’s time to put this one back on the bench.
The suspect part will eventually come out. I think I have enough room in there for a terminal strip for the new diode and resistor(s).
That will be in work shortly, stay tuned!
