The IEC receptacle on the Aleph should be standard & fit any aftermarket PC. I had an Aleph 5 & didn't notice anything unusual about it (tried several PC's) & still have an Aleph P & am currently using the ChrisV Flavor 2 PC on it.
It's possible one of the prongs may be bent or that it's been modified somehow. Scrutinize the jack closely with adequate light to see if there's anything amiss.
