I had to replace the CD Pro 2 drive in my Capital Mk2. No big deal. Audio Aero used a brand of electrolytic capacitors in the power supply. Named "Samwa" . They died!!!. Easy fix to replace, off the shelf values. I ended up replacing all the electrolytic s on the power supply board, all the rest of the caps were branded BC, made by Vishay they tested OK.
What happened to Audio Aero?
They used to be in many digital conversations.
