Confirm the broken resistor IS a 10K ohm, like the one next to it.
The burned one on the side of P/J 206 is 150 ohm.
The manual instructions for programming the dip switch frequencies has an error in it somewhere as I recall.? Thought I had that figured out a while?back....but no...didn't work as expected.? It was a lot simpler and quicker to just start flipping the dip switches and checking the results using the TR-7.? You get the hang of it quickly that way and see your results/mistakes right away.? Forget the mathematical way!
I have those Capar electrolytics?in mine too, as do you.? I need to change them, though the RV-75 is working fine....for now.

Steve,
Yes, good catch! I was so preoccupied with the obvious failed resistor that I overlooked the other failed resistor.
Jim,
you may be seeing power source issues due to failed caps.
My first thougfhts as well. With two failed resistors it makes no sense to simply replace the resistors. I need to find what is causing these to fail. The caps are a good place to start. Can you recommend suitable replacements, especially of appropriate physical size?
Looks like I am going to learn more about the RV75 than I ever wanted to know!
