The main mosfet is on a heatsink on top of the chassis.

The problem is, I now have no output from the amp at all. It's as though the power is turned all the way down. I've noticed that my Hall VVR3 board has a place on it for a resistor that isn't mentioned in any of the instructions I've managed to find.

I couldn't get a reply from anyone at Hall Amplification and ended up buying the board from Barry at Ampmaker here in the UK. But Barry didn't have any instructions for it so I found some online. However, they don't mention this resistor. Does anyone know what it is and whether I should fit a link in its place?
