However, I forgot to unplug the power supply when I'd finished, and didn't happen to go back into the room where it was until 6 days later. On entering the room I could hear a buzzing sound like an angry bumble-bee stuck in a shoe box, and couldn't figure where it was coming from. I tried switching the lights off - no joy. Went over and checked my amplifiers - nope. Then I noticed that the power outlet in which the RAAD was plugged was on. Surely that little red box could not be making all that noise? You bet it was! and what's more when I put my hand on it to unplug it it was really quite hot.OK, I accept I should not have left it plugged in, so my fault there. However, I let it cool down, then tried plugging it in in a different socket, just to eliminate the possibility that it was a faulty socket, but within a few seconds, the buzzing was back, and the unit had started to heat up pretty rapidly.As a result, I simply don't trust this unit. Maybe I just got a unlucky with a bad one, but I'll stick to known brands in future and put this down to experience. ### ⭐⭐⭐⭐⭐ The company that sells these are well informed and great communicators they answered my questions very quickly and were ... *by S***E on Reviewed in the United Kingdom on 4 February 2017* 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!!! ### ⭐⭐⭐⭐⭐ Excellent power unit for FX pedals *by M***K on Reviewed in the United Kingdom on 20 January 2016* 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. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pt/products/58313009-raad-regulated-dc-9v-ac-dc-power-supply-adaptor-tip](https://www.desertcart.pt/products/58313009-raad-regulated-dc-9v-ac-dc-power-supply-adaptor-tip) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-04-23*
