WoW...thanks for the great suggestions. I have yet to research all of them.
It is a vintage Simpson, 0-100mA, no other writing on the face. It's has a bit of weight to it, if that adds to any speculation about it.
Yes, I will save this meter for a more elegant situation ; my need for a meter is to quickly measure volts and load for:
*4 variable PSUs (in a single box),
*up to 12v / 200mA.......to power guitar fx,
*using a three-position momentary switch on/off/on... (volts/off/milliamps)
*another rotary switch points to which supply output I want to adjust/check.
...the reason for the momentary switch is to keep the meter out of the circuit, except when needed.
BTW: Lackinnj....funny, I was just searching for Jfets today, at my local surplus store....2n5457......they didn't have any.

World politics left aside for the moment, there are several companies producing low-cost panel meters that are getting down into the $20-$30 range IIRC. And for cheaper than that you can get a DMM from an auto parts store to mount and leave, dedicated, in-circuit.
Jesus loves you.
