Replaced the 42VAC power supply - it now runs on 9VDC (or higher) via a 2.1mm socket.

I was originally going to use a Mean Well PSU that output +/-12V and +5V but this КВАНТ (Kvant) board doesn't seem to use one of the 12V polarities anyway.

So we're down to just needing 5V ... in that case, we can either supply it directly via a USB charger & USB socket on the machine, or via a DC plug-pack (say 9VDC) and 5V regulator.

No need to muck around with 240VAC, adding a fuse & socket, connecting the earth, etc.

I'm using a PSU5 regulator from www.ezsbc.com ... these are LM323K replacements and are capable of up to 3A.

Now at 9VDC it is using about 1.6A (14W).
