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.
one can tell the quality of the equipment by the packaging. The SC-102T could not have been packed any better; two boxes separated with bubble wrap and then bubbled wrapped into the final shipping box. I have only checked the operating voltages and dial settings. Considering that I have an input here at about 122 VAC, .the dial should be considered accurate. The unit appears that it was calibrated at 117 VAC. All in all, a very nice looking isolation transformer. I would highly recommend!
Watched a power supply comparison on Old HiFi Guy's youtube channel.
I purchased 2 one for a Fosi Audio GR40 and the other for a Fiio K11 R2R.
The Fiio's switching power supply is 12 volt 2 amp so I did not try it with the Fiio.
Tried it with the Fosi GR40 on my modest near field system that is powered by a Fosi ZA3 amp with Sparko's opamp's, Sony SSCS 5 for mains and Polk Audio RM705 subwoofer.
The difference in sound stage, instrument placement, vocals and especially bass response was shocking. This PSP linear power supply made music like Stanley Clarkes School Day's, to stuff like Dave Brubeck's Time Out to the Who's Live at Leeds My Generation bass solo by John actually sound like a bass instrument instead of the expected performance of an inexpensive subwoofer.
Moving from a Douk Audio P1 tube preamp to the Fossi GR40 preamp/dac made a immediately noticeable improvement. This linear power supply gave a comparably obvious improvement to the overall sound.
Easily the best bang for the buck improvement to the overall sound I have ever purchased.
This variac performs great for dialing down my wall voltage for a vintage guitar amplifier. I added a plug in meter with digital display and makes a perfect set up. I would buy this varian again if needed. Company also got it shipped out immediately. Great experience dealing with AC-DC Powershack!

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.
