The 12 volt ac supply outputs slightly less than 14 volts so under load this works for my application.

This power supply replaces one for a 32 inch fiber optic Christmas tree that belonged to my mother. When I unpacked the box this year, the old power supply fell out and broke. The new one is a perfect replacement, and I was pleased by the quick delivery. Thanks very much!
Appreciate the review Louie. So happy the correct power supply and plug size was a perfect match for your lights.
Arrived on time, I wish it worked because it cost me more to have it shipped then the cost for the Power Supply. Not a happy customer

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!
Thank you for your kind words Marcia. I hope the 2 additional power supply with the modified plug works well with your wonderful lamps.

300VA Isolation Transformer, 117VAC to 117VAC
Thanks for the 300VA Isolation Transformer, 117VAC to 117VAC. The shipping was fast look great and is heavy. transformer was a great price would buy from AC-DC PowerShack again.
This is good and working as expected
I was looking for a switch to put in line for the lamp I built. The connections were an abnormal size and thankfully this switch fit it perfectly!
WORKS GREAT
I’ve been looking for regulated negative center 6v all over the places and didn’t find a good quality until I found this one. It works perfectly for my Grundig satellite 750 just like the one that came on the box with it.

A real person answered my phone call. We discussed my 'problem' and the sales rep. provided me with the information and the right item I needed. I am well satisfied.
Fast, efficient, and excellent price.
Thanks

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.
Works fine. Technical support great!
Great! Will buy more.
