No Cap Kit available, Need to make one from Scratch - Where do I start?
Hello KLOV:
I have a questions regarding cap kits. This isn't necessarily specific to arcades in this particular case, but it can definitely apply to them. I have an old Tandy CM-5 RGB monitor for my Tandy 1000 HX computer that seems to be having some issues. It looks okay, but after a bit of time on I can clearly smell the distinct odor of burning electronics. Also occasionally the video signal goes to just blue.
Given it's age, it's probably reasonable that some caps probably need replacing. However, I have not been able to find anywhere online that sells cap kits for this particular monitor. So it seems I'd have to assemble my own. My question is where do I start?
I know that I obviously need to check all the values and types of the capacitors on the board and then order suitable replacements, but is that really all there its to it? Most of the time when I have gotten cap kits in the past, they usually don't cover ALL of the caps on the board. It seems filter caps are typically bought separately, but even beyond that I've noticed that the kits for the Electrohome G07 from ArcadeShop, for instance, replace all but a few caps on the board.
Why is that? Are those just caps that aren't particularly known for going bad or aren't critical? Is there something else that goes into making a new cap kit for a monitor I'm not aware of?
In general, what should I do if I need to cap a monitor that nobody is selling a cap kit for?
