Maintenance Senior

Ben is my boss who authorized the purchase. I'm Derrick "Senior Maintenance" that chose and uses the power supply, and it is functioning nicely. In addition: the customer service was great. Thank you.

DC Barrel Plug Adapter to 2.5 x 5.5mm RIGHT ANGLE plug from 2.1 x 5.5mm
Serves a need very well

This connector allows one to adapt a DC power need to a slightly different size. I had a Line 6 foot switching pedal power plug I needed to match up with a Strymon power cord connected to the Strymon Zuma power supply. This allowed me to match them up without stripping fine wires and soldering them together. It's maddening why companies continue to use different male and female connectors and it creates hassles. It's the same with computer USB names and varieties. Standardization would be appreciated.

300VA Isolation Transformer, 117VAC to 117VAC
A Workbench Essential

I use this to isolate my Powerstat and Dimbulb on my workbench when testing electronic gear. 300 VA is all I need because of the Dimbulb limiter and it works as advertised.

A Very Nice Power Supply

This is my second purchase from AC-DC Power Shack, and I'm very pleased with both! This variable power supply is perfect for my needs. It was shipped very quickly and well packed, and at a great price. I will definitely be doing business here again!

Top Notch Value

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!

1000VA Isolation Transformer, 117VAC to 117VAC
Better than expected

For the price point, this is a great deal! The order was well packaged and not damaged at all, unlike some other vendors that I have bought from. The transformer was not advertized as a toroid, but it is which is a big plus. It is properly mounted to the case with a good bolt, and isn't going anywhere. The case itself is decently thick sheet metal. Solder connections on the inside were good, wiring was tidy, and nothing needed rework. Input side had a two-pole switch and a glass fuse. Output has a switched breaker. All in all, this is a really nice and well built unit and you can't beat the price.

Well constructed and accurate.

I purchased this as an isolation unit and got the very act as a bonus. The construction exceeds my expectations and the operation of the variac seems very accurate to the display. Works best when I go above the voltage I want and come back down.
