QRP Labs QCX-PA2 amplifier case

<p>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.</p><p>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.</p><h3>Print Settings</h3><p><strong>Printer Brand:</strong></p><p>Wanhao</p><p><strong>Printer:&nbsp;</strong></p><p>Wanhao Duplicator i3 V2</p><p><strong>Rafts:</strong></p><p>No</p><p><strong>Supports:&nbsp;</strong></p><p>Yes</p><p><strong>Resolution:</strong></p><p>0.2</p><p><strong>Infill:&nbsp;</strong></p><p>20%</p><p><strong>Filament:</strong> Generic PLA Match to your QCX?</p><p>&nbsp;</p><p>&nbsp;</p><p>&nbsp;</p><p>Category: Electronics</p>
