SA-2060 Tuner Sensing Unit Calibration

[Gary Harmon]

Yes, I know that the sensing unit comes calibrated from the factory and there
are no instructions in the manual.  In fact it says to leave it alone.  I know
all that.
Anyway, I am reverse engineering a sensing unit that has external pots mounted
to provide easy adjustment.  No, I have no idea why.

The schematic shows four variable resistors and an adjustable capacitor.

R104 is the LOW REF adj and R107 is the LOW FOR adj.
R105 is the HIGH REF adj and R106 is the HIGH FOR adj.
C105 adjusts something.

Has anyone perfected the adjustment procedure for these 5 adjustments in
conjunction with the front panel controls?

Thanks in advance.
