Power supply advice please (I live in the UK)

The TTi supplies have an output on/off switch. This also acts as a set/run switch so you set the limits with the controls. No shorting required. That annoys me too.

I bought one of the Sparkfun ATX Binding Post kits and added it to a supply. I haven't used it but it's around here somewhere. Fortunately, there are fuses in each output. I wouldn't use one of the newer 1.5 kW supplies.

Here's an open frame +-15V supply that should work well for dual rail op amp projects

Here's a neat little breadboard supply for 3.3V and 5V when it comes back in stock:

Nothing wrong with building one yourself. Back in the eighties I built my first power supply from a circuit in one of the Forest Mimms books (with Radio Shack parts of course), and I used it for years. At some point I took it apart to scavenge the enclosure for another purpose. I wish I hadn't now, but I did keep a few of the parts. I didn't realize how bad it was until I came here.

That’s sort of what mine looked like although yours clearly had less fires.
