[Swansea Hackspace] bench power supply

[Ceri Clatworthy]

just had a look at the PSU, (would not load on my phone ?!!?!?!)

Looks suitable for you, BUT the current is ONLY adjustable with a
screwdriver, !!!!!

I would recomend Farnell / RS / CPC etc not ebay ..

72-2695 -  Bench Power Supply, Linear, Adjustable, 1 Output, 0 V, 60 V, 0
A, 2 A  is £77 and from Farnell..

have not checked the specs,

but from Farnell, you can get refund / swap if it goes BANG.

>From eBay WHEN it goes BANG you are screwed !!!
