Mahlon,

Just looked at the manual downloaded from BAMA's website. Nothing in it on
calibration or repairs, but it does have a parts list and schematic.

Hello, list.

Was given a Sprague Tel-Ohmike TO-6A yesterday.  Free was a good price
in this case, since all of the paper capacitors in the unit need to be
replaced, and also because the meter is blown and needs to be replaced.
Not unlike what I went through with my Heathkit capacitor tester a while
back (the two "standard" paper capacitors in it were so leaky the bridge
never balanced; same thing is going on with the TO-6A).

Has anyone ever run across a calibration procedure for these?

regards,

Mahlon - K4OQ
