Default Re: Acbel API1PC36 from an old Mac

Thanks SiriusHardware. I am very comfortable with thermionic valve technology, but freely admit that I am stumbling in the dark with solid state SMPSU issues. Please can you indicate by resistor numbers from the attachment in Post 7 which ones are start up resistors? Also I'd have thought that if there were a problem with startup resistors, the PSU would also fail to start on the bench; since it does in fact start reliably on the bench, maybe there is a problem that only occurs when it's on load. Thanks Timbucus, another useful tip. Cheers, Jerry
