potentiometersymbol [~]
I cant figure out which pin is the number 1 on the potentiometer and variable resistors within this schematic. I would guess that the circle with a slash through it is pin one but I'm not sure. Any help would be appreciated. Thanks in advance!!! Schematic link below.

It seems this potentiometer belongs to the F10KV6 series by Favor (or Polyshine). It falls under the category of "rotary joystick potentiometers". The form factor seems to be the same as the original (even though the resistance could be different). The ultimate confirmation would be to obtain one, but since the minimum order quantity from the suppliers found is 1000 units this is unlikely.
SE Note: Since this is along the lines of the information I was hoping to obtain I am posting this as an answer rather than a comment. If it is inappropriate for me to do this, feel free to take whatever corrective action is necessary.

If the bottom part of the pot is 7.8K then the top should be 10K-7.8K = 2.2K.
For the feedback voltage to equal the reference (2.495V), the voltage at the top of the divider would have to be (10/7.8)*2.495V = 3.20V.

Trimpots especially multi-turn pots are often numbered with pin 1 being the CCW position and 3 for CW.
Since it is not marked (as one would hope) on the schematic, you may hope what see is the minimum position is pin 1 (CCW).
This "standard" was started by Bourns and but it's hard to say if it is still universal.
