These panels and PCBs are for sale to DIYers
They are the same as my 4U panels but Eurorack sized; screenprinted brushed aluminium.
The singles are 8hp : AU$20
The quads are 26hp : AU$35
It is hard to get a picture of the quad panel, as you can see it looks completely different, depending on the light & background, it is the exact same panel in both pics.
