I have one, Mastech HY3005D-3 Power Supply, from many years ago.
Never really tested the noise of the thing.
But it's kinda big & clunky. Dual outs with a fixed 5v too. The output selection is good for my needs, I often run low level control ckt's along with higher power stuff, and sometimes do need the fixed 5v too.
That said, I am looking for a replacement in effort to downsize the footprint on my bench. And yes, I prefer simple dial wheels for adjusting. Any suggestions for $250(US) budget?
