A client brought in some vintage Altec line amp and PSU modules for a recap and hookup but no cables came with. Are these just mini xlr that I have to take the housing off of the male end and heatshrink?
Aha correct! Marked on the rear of the connector. Looking at ebay looks like it must be part of 97 Series. Sure are a lot of 3 pin variants out there. Might be easier / more cost effective to swap to mini xlr vs playing the guessing game on mouser.
