Need guidance on Classic II repair

I'm still having some problems with my Classic II. After replacing DP3, DP4, CNY17G-3, and TDA4605, everything was working perfectly for a few hours. Voltages were rock steady. After leaving the computer on for a few hours, voltages would start to drop. I'd work on it some more, and voltages would return to normal only to drop after a period of time.
I've decided to replace all of the other capacitors on the analog board:
CF1
CF2
CF3
CF4
CL1
CL11
CL2
CP3
CP34
CP37
CV2
As I was removing these capacitors, I noticed that the RF2 resistor is chipped. I am not sure if the fact that it's chipped will cause me any problems, but I would like to replace it. I have really tried to teach myself how to read the markings on the resistor, but I don't fully understand them. I would be most appreciative if someone here could help me identify a suitable replacement on mouser.com. The markings are:
A (or is it a delta symbol) 1W
202G
16
I've attached pictures for reference. Please help.

Ok, so right after my last post, I remembered that my multi-meter can test resistance. I hooked it up, and this is what it is showing. I'm thinking that the resistor is functioning properly despite being chipped. Thoughts? Should I still replace it?
