[R-390] Speaking of TO-6As...

[Mahlon Haunschild]

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?
