I bought the wrong voltage, l need a 9v cord
Hello,
Let me reach out to you and see if we can find the right match for you. For faster response in the future, please email us directly or call us next time. Thanks!
Used supply with 12vdc relay to make a trigger for amplifier. Needed relay because supply has a capacitor that takes a long time to bleed down in this application.

The device appears to be solid and well built. It's the only unit I've found that has both a Variac AND an Isolation transformer in one unit. It's roughly half the price of buying both units separately (not to mention the reclaimed workspace). As near as I can tell, the output is indeed isolated from the input, as claimed, including the ground. I'm just a hobbyist, not an electrical engineer, so please accept my opinion in that that context.
I had to get Chat GPT involved before I found this adapter, and it worked. I'm happy :-).
Custom length power shade charging cables were made properly, worked properly, were delivered quickly, and reasonably priced. Hans was great to work with
AC-AC Power Supply 6V AC @ 1670mA; 2.1 x 5.5mm
We have some older hallmark ornaments that were designed to plug into the string of tree lights. But the lights changed and the ornaments would no longer work. This power supply works as a perfect substitute.
Works great! Thanks
This works perfectly on my effects pedals that optionally take 12v for more sonic headroom (or similar).
I just ordered more.
The power supply works as advertised, and my Christmas Village is well lit now.
Very well built. Works perfectly. Good value.

Works great 👍
I ordered a 20 some pound transformer and was thinking I would be lucky if it arrived unscathed. It was in perfect condition mainly due to the outstanding way it was packed. Triple boxed with foam between each layer. It was truly gorilla proof. And the product inside is well made and reasonable price. What a contrast to the business as usual companies that I normally deal with. Thank you.
A genuinely amazing buying experience with AC DC Powershack. The isolation transformer was packed with meticulous care—thank you! Owner Patrick is fantastic and made communication effortless. Top marks all around.
Works great, does just what I was looking for it to do.
Exact fit
Old Guy Hifi sent me after I researched about linear power supplies on YouTube. I have it powering my Dac. I reccomend highly 👍
I purchased this for my fiber optic Hummingbird lamp because it has a color wheel synchrous motor in which requires the above power adapter. This company is the only company I found that carries these adapters. I bought one, and now have bought 2 more, one for my sister who has the same lamp and another for me, because I recently purchased another fiber optic lamp. Hans was very helpful and I truly appreciate the help he provided. Thank you Hans!
Most guitar pedals and effects boxes are standard 9V center negative DC, but my Alesis Phlngr actually needs 9V AC. I had to find the right plug size which ended up being 2.5 mm inner diameter instead of 2.1mm like this adapter. This site also sells the converter from 2.1x5.5 mm to 2.5x5.5 mm that allows me to interface with this unit. Works as intended.
I bought this adapter for my Boss SE-50 since I did not want to spend $40+ on a giant brick known as the BRB-120. I had one of the original Roland power supplies back in the day and hated how much space it took up just for a half-1U rackmount. However the plug on the AC/AC adapter I bought here is 2.1mm x 5.5mm so I also got a converter on this website to adapt it to the 3.0mm x 6.3mm plug in the back of the SE-50. I have confirmed this to be operational, and a less expensive shoehorn for the BRB-120.
