I had to dismantle my shack to extract my only 12v supply to bring to the meeting the other night. Very disruptive. So on the spur of the moment I ebayed this one from Makers Hut. 12v, 20 amps, light as a feather, and cheap as chips. But what I didn’t notice was the exposed mains terminals!!! Ok for a fixed installation I suppose. Rig pictured alongside the PSU is to give a sense of scale.
