Re: GEC Selectest Super 50 Mk2 fifty year MOT
Mine is a Super 50 Mk 111. Voltage scaled 0-20 and 0-100.
Various ranges differ between current and voltage, not just a simple 1-2.5-10. Definitely not a 1-3-10.
I used to have a "p[ink" one, but must have sold it years ago. I had a few (ex-CTV rental company) "mini" Selectests. Forget the actual designation, but save 50k ohms per volt, limited ranges, and smaller movement of course. All well past their best as you can imagine. I think I still have a couple. Plenty good enough for outside service I imagine.
