Multi-output PSU reliability report

I've had one of these for about 18 months:

I was using it yesterday afternoon, no issues; took it to the jam and it was dead when plugged in.

The dead bit is the 12V 1A wall-wart SMPSU, so I'll have to buy a new one of those and wire it into the box/regulator.

is £5.99 delivered.

One reason for having old-fashioned batteries in pedals, though - as backup for when your PSU dies.

I use onespot to, it's cheap and noisy, but i like to play loud or with lots of fuzz. I heard that if you use a boss tu2 on the daisy chain it filters the noise from the onespot, is this true?

Never had a problem with mine except with the RE-20. I even powered a pedalboard with a Deluxe Electric Mistress with the 1Spot.

seriously, get a pedalpower 2+ or the new ISO5

I had used one-spot for over 4 years and pp2 saved my rig.

TU2 can cut down some noise from one-spot before the gain pedals (fuzz/drive), but some pedals just hate TU-2 in front.

And the hiss is still there taking over guitar signal.

To me effect chain noise kills all the fun of the fuzzes. I wouldn't use any pedal now if there's no voodoo power.

I've got a dunlop power brick that i've been using for like 9 months. It works well, very quiet, has lots of inputs and two different voltages, and several different connector styles to fit various pedal inputs (all modular). I don't think you could ask for much more out of a psu.

PM'd, Rob's a great guy.
I took the SMPSU apart and found the input fuse blown. 2A time delay, about 3.5mm x 11mm, wire-ended. Maplin does nothing like it, so if I wanted to try a repair I'm looking at a minimum order value of £5-£10 on-line. Another piece of electronics for the tip...

Check a plumber's merchant? That seems like a short blow fuse I had to replace in the routing board on my boiler last Xmas.

My one spot died on me at the end of last year .... I bought some rechargable batteries for home use..... lucky for me I don't use power hungry pedals like delays, so they last for ages without being recharged.

Interesting. Ta.

Had a 1spot for about two years or more now. Heavy gig and practice use without any problems at all. I just recently bought another, rebadged by Rocktron as I've given the VS one to my brother. There are at least three brands of these power-all power supplies now, Visual Sound 1spot, Behringer and Rocktron. I think Stagg have just released one too, which is half the price of the others.

I am wondering whether it's worth the extra £10 that it costs more than the Visual Sound, Behringer and Rocktron versions, though. I assume it's pretty much identical?

Behringer already have one out?

I was looking forward to them making one for like, a tenner or something, or maybe one so cheap that they actually pay you for the botheration of having to carry it home.

Disappointed.

£30 delivered isn't that bad, to be honest. The Stagg one is £10, but without any additional cables or daisy chain. Buying them would probably make it around £18 or so.

I was thinking about my Visual Sound though: I must have bought it years ago because I ended up getting it from America because absolutely nobody stocked them here, or if they did, they were £40 or something. From the US (and the store stocked both the UK and US plug options!) it cost about £25 with P&P. I was well chuffed.

the carl martin cost me £29 quid with all the adapters and daisy chain and shizzle. really long cable too, gotta be about 4-5 metres. think they're all kinda similar.
not had any noise or anything since i started using it. my last power supply (those ac/dc older maplin things) introduce noise and only 3 of the 5 outputs worked.

Well, I've ordered one of those £6 wall warts to get the old box up and running. I also spent some time last night adding smoothing to some old Mascot brand 9V 300 mA supplies that we used to use for network kit. They work fine with Line 6 ToneCore (DSP-based) pedals but have far too much mains ripple for ordinary analogue pedals.

First I tried adding an LM317T voltage regulator; the off-load input voltage of 11V peak resulted in a rather ripply 8.5V - not enough headroom on the input side for the regulator to work properly. Possibly a pair of ultra-low-drop-out 150 mA regulators would work, but I didn't have them in stock

Next I tried increasing the smoothing cap from 2200uF to 4700uF and trying two different approaches to ripple reduction; 2.7 ohm resistor followed by the original 2200uF cap and 1 ohm resistor followed by another 4700uF cap. Neither totally eliminated PSU hum compared to batteries, using the Behringer Ultra Fuzz UF100, but they are at least usable.
