Here’s a question for you old solder jockies. I’ve decided I need a bench power supply, I don’t want to spend too much say up to £60 or so. Am I better to buy a new cheapish one or an old Wier or similar?

Re: Bench PSU
Since they all look the same, have the same spec and probably come out of the same factory, I've ordered this one https://www.ebay.co.uk/itm/ADJUSTABLE-LED-REGULATED-VARIABLE-DC-POWER-SUPPLY-30V-5A-LAB-CE-BENCH-DESK-UK/352518705531?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2060353.m2749.l2648. If it proves unsatisfactory I can always return it. It will only get light use, first job to see at what voltage the RC-3 Looper bugs out......

Re: Bench PSU
I've got an old Weir Minireg which seems OK for most things although it needs a good going over with switch cleaner. I've also used something that looks very similar to the supply that you've bought in my old job and it seemed fine.

Re: Bench PSU
I realise it's a little more than your budget, but I use this Tenma 72-8690 from CPC.
https://cpc.farnell.com/tenma/72-8690/power-supply-bench-2x-32v-3a/dp/IN06094
It's a dual supply that runs up to 32VDC and 3 amps per output, which makes it more than enough for a wide range of analogue audio work. And it can be used as two independent supplies, or as a +/- dual-rail supply

Re: Bench PSU
Thanks Hugh, I'll see how the cheapo one turns out and consider one of the Tenma ones later. I did consider a dual rail supply but decidedI probably would not need one ion the foreseeable future (watch me proved wrong almost immediately 
).
And thanks James, in the end I decided on new to avoid any dodgy switch/pot issues and to have the opportunity to return if it turns out to be poor.

Too out of touch to be helpful but I do wonder why they Photoshop the display in the listing?
I think I got my supply from Maplin but it is consigned to a cupboard along with an old Farnell (high current) supply I sometimes used to 'light up' pencil 'leads' to amuse the kids...
