I’ve done some more work on the amp. Fixed a bit with the fan and feed through capacitors for different voltages. Also added the 12v step down converter.
I also milled a box which will be used to turn on/off the remote, amps etc. This box will just be a switch box which will routed through a control card, making it possible to also control it remotely. That way we can turn on/off stuff easily from the shack and remotely.
