Who all had or has one of these?

Everywhere I have worked had some of these Simpsons around. However, I personally like my model 630 Triplett. Hard to beat an analog meter movement for spotting intermittent circuits, especially in automotive circuits. Try that with a digital meter!

They are both very good meters, I have a few Simpson 260's and a Triplett 630.
There is a model Triplett 630 - NS or NA that is very high ohms/volt - I don't
remember which but it's the next best thing to a good VTVM. Either way
a Good Analog meter is good to have and know how to use....
I also have one of those super High Ohms/volt Simpsons
also a good meter.

Triplett 630s were used in my VoTech electronics class in late 70s for freshmen's ohms law classes.
We also had EICO 232 VTVMs, which I used on the electronics. They did not yet have Fluke, Beckman and other DMMs.
Most importantly, Instructor showed loading effect of even a good quality VOM on small signal and oscillator circuits.

Simpson 260 has a smaller visible scale, and extra jacks/functions electronics techs don't necessarily appreciate.
I have a 260 (unrestored) and a 269, which is oriented toward RF techs and has a huge meter for touchy adjustments.

It was a great meter to put in the hands of everyone else from auto/farm mechanics to appliance repair to plant maintenance, provided they are aware of voltages and arc-flash risks at a specific location and use proper protective gear.

My particular Triplett 630 is a 630-NA. It has a range doubler switch which gives you twice as many voltage ranges. Very helpful.
