Old Guy Hifi sent me after I researched about linear power supplies on YouTube. I have it powering my Dac. I reccomend highly 👍
5 stars. Works as intended.
Thank you for your positive review! We're glad to hear that our AC-DC Linear Power Supply is working well for you and meets your needs. Thanks for choosing our product!
Bought this to replace the stock PS for my FX tube buffer pre-amp that I paid less than $30 brand new several years ago. Back then I replaced the Chinese tubes it came with for USA made GE tubes for around $28. I have a WiiM Ultra and Sony X800M 4k bdp that plays SACD, DVD-Audio(I have a collection of physical media). Both the Wiim(USB & optic) and the blue~ray player(digital coax) are linked to my Geshelli Labs J2S DAC with Sparkos op-amps. From there to a Schiit LYS(RCA switcher), 1 line going to the FX preamp then to my late model Sony ES AVR. I have EMF filtering on my surge protector, other quiet power supplies, ferrous chokes, etc, but nothing expensive. Anyway, now my system sounds better than ever. Subtle, yet beyond placebo to my ears. Perfect match for my use case. This PS is well constructed, allows my devise to achieve its potential, and it’s priced so low it doesn’t make sense not to try it. Satisfied customer, will shop AC-DC Powershack in the future. Oh btw, they shipped it immediately and it arrived in a couple days. Excellent service!

Nice compact power supply
Great customer service and support I would buy again for I’m them
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!
This is a great machine for my bench work would highly recommend
Perfect for my needs
This is the perfect addition to my shop for doing vintage radio troubleshooting. The isolation transformer works fine and appears to be well made.

Now a staple component to my electronic desk.
This is a real isolation transformer. Keeps me safe when doing my repairs.

I can’t believe it didn’t come with cables.
It’s pretty much useless without them.
I had to order them from someone else because I won’t order anything from your company again.
Unless you would like to send me the set they should have came with.
Hi there,
Thank you for your purchase. We apologize for any inconvenience caused by the product not coming with cables. Unfortunately, they do not come with any cables nor were they advertised or shown to include any cables. We value your feedback and will take it into consideration for future improvements.
Tested supply before connecting to radio while rated for 15 volts, it measured 20 volts making it unusable. Since I had to replace the barrel connector for proper connection, I'm stuck with it.

Hello Joseph,
Sorry to hear the power supply wasn't a match. Unfortuately, all of our AC/DC linear power supplies are unregulated unless otherwise stated. A no load on a non-regulated power supply typically would measure about 1.2-1.3x higher.
Regards,
Hans

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.
Nice compact power supply
