I have a couple of linear PSU's (Weir, both 30V-2A, 15V-4A) but they
are both old and are now non-functional / iffy and I was considering
something newer, lighter, smaller and with twin digital displays (on
the Weir's you have to switch between displaying V and A).

There are loads over the normal suppliers but I wondered if anyone
here had got something reasonably recently that they could recommend?

It's for general use, (temporarily) powering 5/12V things, charging
the odd battery and the like.

A 10A capacity might mean it can batter handle a 5A output, quieter
the better (some use small heatsinks and small fans) and ideally under
say £100?

I did look at kits (good to know you have the cct diagram) but that's
probably not best done with a SMPSU and linear stuff also seems to
require large heatsinks and heavy switching devices, all taking extra
time to source/ build (unless a complete kit with case / hardware
etc).
