Great idea, this one! Might be able to trade or swap stuff, I've got a ton of spare parts lying around, capacitors, switches, LED's, with no useful destination.
Kicking it off:
Offering parts from a Beocord 2000 (model 2921, August '83), notably boards #1 (power supply/control) with heat sink attached, #2 (aux. control), and deck mechanism without motor or belts. If you're quick to react, the main power capacitor may even have some charge left when you get it in the mail!
Boards were removed in working order. I'm keeping the chassis and boards #3 and #4 (LED's and touch) for a future project.
