When you buy one of the new Dada 405 High-end boards with OPA604 or with OPA627-chips we will buy your old 405 PCB-board, even if it's broken.
We offer 30 Euro for a 405-MKI board and 40 Euro for a 405-MKII board.
When you buy a Quad 303 High-end Driver-board or Power-supply board or the 303 High-end board & capacitor kit we'll offer 20 Euro for the old driver-board and 10 Euro for the old power-supply board.
This way you can easily upgrade your Quad yourself by simply swapping the boards.

ReplyDeleteDo you still operate this scheme and, if so, does it apply to pre-11500 303's?
