[Hammarlund] GR 650-A Saga!

[jsheetz]

As a semiresponse to my previous post I have just made
an examination of the action of the Main Dial pot on
the General Radio 650-A Impedance bridge. As near as
I can determine, the eight alignment screws for the
main dial would be set at .05, .58, 1.25, 2.25, 3.5
5.3, 7.7 and 11.0 on the dial. This appears to be
right where the tracking "finger" would be in line
with or most affected by each adjustment screw. 
I have no published information on this procedure.
