Ok, so I have almost fixed one of my Galaga PCBs and I am considering replacing the resistor packs with Raymond's renew kit. Well, I have tried to measure resistance to avoid replacing all the packs but only the ones that are off (too many legs to desolder/solder, even with a Hakko desolder gun)
I am stumped that almost all the 2.2K ones in the video PC board show values half that. Also, RM4 which is supposed to be a 2.2K reports values of 2.1, .345 or 1.1K on some of the legs. HOWEVER, it turns out that these are the same values of RM4 in my fully working Galaga board...
I havent measured the packs on the CPU board yet.
What's is up with that?
Thanks for any pointers guys...
