General ViewsThe fabricated heatsink for the LM7812 can be seen at the top left corner of the PCB in the image below.As the potentiometers I used didn't have any "mechanical" attachment to the PCB, I wasn't happy allowing the solder connections to flex so I stiffened their mounting with a small aluminium bracket attached to the PCB.
