QRP Labs QCX-PA2 amplifier case

This is a very simple chassis to support a QRP Labs QCX-PA2 power amplifier. If you build the amplifier kit without an enclosure, the large heat-sinks are joined to the PCB only via the tabs of the power transistors, so everything can move around a bit. This chassis gives everything a bit more support, gets the heatsinks off the bench top (which is a good thing if it's metallic, even if painted) and gives the PCB a bit more protection. The amplifier should just drop in if you've assembled the PCB according to the instructions.

The first file is the plain enclosure. The second has a pair of tabs with 4 mm holes for fixing screws - I found it useful to be able to attach the amplifier to a wooden board along with the QCX, to keep everything in one place.
