I'm sure mine were Amperex but my supplier is now showing these ones.

They match the look of the Headphone socket perfectly.

Where did you find the recessed RCA input cups?

The Amphenol ones are at PartsExpress, and the Neutrik ones can be sourced just about anywhere, but I know off the top of my head that Markertek carries them.

They're called "D-flange RCAs", for whatever its worth
