I really wanted to like this AC-DC Linear Power Supply 9V DC @ 1000ma; 2.1 x 5.5mm (+) center polarity but it would blow up my equipment if I interconnected it with this thing !!!!!!!!!!!!!!!! Bye now !!!!!!!!!!!!!
So sorry the power supply was not a match for your needs. A linear AC-DC power supply (non-regulated) will always read about 1.5x higher on a no-load read. The 9VDC will probably read about 13-13.5VDC. A regulated or a switching type power supply (are always regulated) will give a constant steady volt reading with a +/- of 0.2V within its stated voltage.
Whereas an AC-AC linear power supply will read about 1VDC higher on an open/no-load read.

6V AC-DC Linear Power Supply
Works like a charm for my Grundig 350DL as I lost the original years ago. Thank you AC-DC PowerShack.
Easy pleasant transaction, great quality and great value. This machine will be used for a power supply for a homemade electrolysis tank. Don't be afraid to purchase from this company.
Thanks to this AC/AC adapter, this Zoom RFX-2000 unit was brought back to life.
Thank you ACDC PowerShack, excellent service.

12V AC @ 1000mA Power Supply 2.1 x 5.5mm
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!

Works for non-standard audio effects
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.

Replacement for BOSS SE-50 Supply
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.
