Reply to broken sensitivity dial broken - jog issues

Hi , like others I am sure, I have broken the variable resistor at the back of my unit that adjusts the sensitivity for the jog wheel . Does anyone know the part # / resistance / manufacturer?

Also, leading up to me breaking the dial, i was not able to get the right jog to respond to my touch (using all settings from min to max at the back of the dial), and the light of course was very intermittent, where as the left jog while I tapped and untapped no matter what speed the light would go on and off with each tap and of course the response of the platter was OK. The jog rotates ok, no stiffness or grinding etc.. by following DIY repair guide do you believe i am able to fix this this issue?

Oh while the the jog LED and the response was not working the data light always lit up to the touch... maybe this might spark some ideas.

-1.4 firmware
-TP 1.2.7
-3.6.4 TSI

In the mean time, I would still like to use the unit.. when scratch mode is turned off , i can use the jog for pitch bend ok (for the most part), but seeking through a track is slow and painful, where as the working jog on the left seeks fast through tracks when the scratch mode is either on or off. How can I speed the right jog up ? Does this rely on the touch sensor ?

Thank you! hope this post was not to long, but I wanted to paint a full picture of my problem
