Hey folks, I've now scanned the instruction manual & schematic to the Radio Shack (a.k.a. Micronta) 22-204C analog multimeter. This is one of the best meters Radio Shack ever made in my opinion. I bought mine in 1984 and still use it several times a day every single day.

The schematic was scanned at 600 d.p.i. resolution so you can enlarge it.
There's a guy on you tube who's done a 4 part series on how to repair this particular meter model.

Also now available is the Archerkit 28-4014A assembly, calibration, and user manual. The 28-4014A is the exact same meter as 22-204C except in build-it-yourself kit form.
This manual can be used to service and calibrate the 22-204 meter also.
