Is this the same cable that caused the first mishap?
Weâre scratching our collective heads as well. I have our production engineering team on the case.

I donât know. I emailed Mark yesterday afternoon when I found the disconnected cable but I havenât heard back from him since.
Iâve had something similar happen years ago. Not with a regenerator, but a CD transport. Thatâs a standard commercial ribbon connector. One might think with that many pins engaged it couldnât be knocked off in transit. But sure enough thatâs what occurred in my CD transport. It wasnât a power on problem that was the symptom in that case, but the transport controls were unresponsive. A multi-pin ribbon connector had come loose. In the aerospace world I work in all multiple pin connectors are secured with screws (and even staked). Transport shock and deployment platform vibrations are two of the reasons we do that. One more observation: that ribbon spans the unit and doesnât look it has a lot of relief. Could be why it has a tendency to pop off.
Securing that connector with something sounds like a good idea.
A little dab of silicone caulk would work nicely.
From that photo I can now see why there is so much flex when I plug in one of my $3000 power cables into a socket on the P20. I am alarmed to see the sockets APPEAR to be soldered to a rather thin printed circuit board. (With metal backing)

These ribbon cables are not very flexible and there is a significant unsupported length plus uneven side tension, perhaps it has simply wiggled itself out from vibrations during transporting?
Maybe regular participants of this forum take it for granted, but I am extremely impressed by PSAâs involvement and response to this posted issue: a used P20 purchased from a 3rd party and the extent
PSA went to to make things right.
That goes a long way in my book.

None of us take PSA service for granted. Purchase of my BHK Pre via a trade through my local dealer (when PSA was still supporting a B&M network) was made as smooth as conceivable with PSA customer service working directly with my salesperson to make it happen. The good news is the service is first rate after the sale, not just during the sale.

Just a follow up to this issue from last year.
The P20 worked flawlessly since I found the source of the problem was a disconnected data cable to the front panel. I decided to sell the unit on US Audio Mart this month since I needed the cash. Two prospective buyers pointed out that the top 2 screws on either side of the unit were missing. I must have left the screws off in case I needed to remove the lid again and then forgot where I put the screws. I contacted Mark Simpson at PS Audio and within a week, I received from him 4 replacement screws at no charge even though I offered to pay him for this.
I wanted to share this to let you all know how appreciative I am of PS Audioâs customer service.
Enjoy the music everyone!
