I have an old Radio Shack multi meter, 22-166A. I talked to Radio
Shack
I don't know there part numbers by heart. What exactly is this.
Digital, with a needle?
about betting it fixed, and they said that for something this old
I'm pretty much out of luck. Does anyone here know of a source of
parts and repair for old Radio Shack equipment?
What he said. What's wrong with it? Does it work at all?
Is one setting not working? That could be a burned out resistor. It
might say on the resistor what the value is, but if that part might be
burned off. You maybe can measuere the resistor for the settings on
either side, and the one burnt out with be the, I forget what you call
it, but if the ones left are 20 ohms, 200, 20000, 200K, the one in the
middle that is burned out is 2000.
Problem is, you can't just drop a new resistor into a meter and call it
done. The resistors inside them are high-precision: at least 1%,
sometimes more, and sometimes weird, completely non-standard values.
(You might get lucky and be able to replace one, but that's not a sure
thing.)
We need to hear from the O.P. just what's wrong with the unit.
Besides, it may be that it just isn't worth it to fix it. Radio Shack
(Micronta) multimeters are mediocre quality at best. Better to get a
*real* meter, like an old Simpson, Triplett, etc.

Personally, I like Vista, but I probably won't use it. I like it
because it generates considerable business for me in consulting and
upgrades. As long as there is hardware and software out there that
doesn't work, I stay in business. Incidentally, my company motto is
"If this stuff worked, you wouldn't need me".
