RAAD regulated DC 9V AC/DC power supply adaptor tip negative center class 2 transformer replacement for boss PSA-230 PSA-240 (500mA)

Excellent power unit, works well with the Ditto x2 looper, No hum at all when connected and in use, tough enough to withstand gig use as its well constructed. The red colour makes it easy to find in the gig case and more important that's its the correct power unit for my looper or other pedals. Don't buy cheap as I have done in the past, you only get what you pay for. I can recommend this.

This is an excellent psu. I've bought several RAAD psu for my pedals. They're very low noise and reliable. I've found them perfect. I think they possibly use some old school electronics inside that lend themselves to low noise and long life. I always buy the highest rated current version so there's less risk of over-heat or volt-drop. Great price too.

Get one of these!!! you wont regret it. Makes no noise and is well made. I spent a lot of time trying to find a decent unit and stumbled across this on amazon. The company that sells these are well informed and great communicators they answered my questions very quickly and were very happy for me contact them if I needed further advice, this coupled to the great people on the amazon community that provided great advice meant this was the psu was the one for me. I have just hooked it up and its as quiet as a mouse great in a studio and is very well made Brilliant!!!

Not brilliant tbh For some reason the pre-amp /headphone amp that I bought it for, which specify this voltage and amperage, freaks out and shuts down when this power supply gets warm. It doesn’t do this on any other power supply. Frankly I have chucked it at the bottom of a drawer somewhere as I can’t use it for the purpose I bought it It’s just wildly unstable. Shame.

Works well no noise good product

Bought specifically for use with a BOSS RC3, and worked fine. I daisy chained it into an old multi effects unit and noise that I always had with the unit just went away.

Runs 6 pedals no problem, no buzzing, holding up well, seems quality.

A proper power supply, not one of those noisy switch mode PSU's. Pricey, but like everything else, you get what you pay for.
