Not correct on the amperage rating, at least according to the service manual for the CPS150 on the Soundcraft website…see page 10 of the pdf found here:
https://www.soundcraft.com/en-US/product_documents/cps150-user-guide-pdf
The +/-17V audio power rails are rated at 1.25A each. Where do you see they are 2.1A?
And, wait…you originally said the two power supplies, the CPS150 and the DCP200, had different interface connectors, but you’re now retracting that? You didn’t really know that? Are you saying you know for fact the are the same or do you really not know? Just because they are “multi-pin” doesn’t mean they are the same. There are literally thousands and thousands of different “multi-pin” connectors in existence.
