Piezo Amp HV Supply Rev A PCB has arrived

The PCB has arrived and Sierra have done their usual high-quality job. I'll be loading the PCB
manually, except for the switchmode IC U3. This is a DFN package, and can only be soldered with
tools that I don't have. Fortunately a friendly contract-manfacturing company that my employer uses
will do it as a favour - yay!

I'll be posting more pics of the loading of this PCB soon.
