We often get the question if we can supply the plastic clips for mounting the Quad 303 driver-boards and power-supply boards in the chassis, as they can break off while removing one of the boards.
In fact a simple and cheap alternative solution is using 4 mm plastic cable-ties, like in the pictures.
The 303 in the pictures belongs to Ad from the Netherlands and has been fitted with Dada High-end boards, new MJ15003
transistors and better internal cabling.
