Jim,
Thanks for the quick reply and photo. Yes, based on your photo, it does look like 10K (keeping in mind that I am looking at the RV75 for the first time ever!).
I am inclined to tack in a new resistor to see if this restores proper operation. If not, I lack the skills, soldering tools and test equipment to go further. Also, this RV75 has plenty of?"CRAPar" capacitors. I am looking for someone who will take on the task of further troubleshooting, appropriate parts replacement and testing. Given the scarcity of the RV75, I am inclined to want to fix it rather than junk it. Any suggestions appreciated.
Best,
RB
