I have an Apple II Plus with a replacement (//e) PSU installed in it (Dynacomp model). About two months back, I started having power problems that manifested in a dim screen and the disk drive not having enough juice to run the stepper motor. Not knowing what I'm doing, I purchased a recap kit from Console5 and recapped the PSU, which seemed to resolve the problem.
I exhibited the II Plus at VCF East two weekends ago, and it was powered on for the majority of three days with no cooling fan -- probably the most its been used since 1994. I transported it home and it continued to work fine for another three days. Then on Thursday afternoon, I started seeing those power issues that I had originally encountered two months ago. A coworker helped me over the phone and we determined that the 12V line isn't producing enough power (my multimeter read ~8.5V). However, I don't know much about working with PSUs, and am unsure what steps I would need to take to identify and then correct the source of the problem. Would any of you folks know where to begin?
