1000VA Isolation Transformer, 117VAC to 117VAC
ISO 1000

Seems to be working as it should now. There was a humming or buzzing coming from it when the front switch is off. Not sure if this is normal or not. If the just leave the front switch on it doesn't do the humming or buzzing. The rear main power switch has to remain on per my bench setup so it not easily accessible to keep crawling under the bench to reach up behind to flip the switch. So far it's been working great with my gear as expected.

Amazing Customer Service

I was having trouble finding a power supply cord for my lamp. I wrote an email to AC-DC Power Shack and Hans wrote me back within the hour and helped me choose this and the right accessory. Amazing customer service - highly recommend!! Shipping was also fast.

Decent Quality, Good Service and Affordable.

Heard about the AC-DC Powershack on a YouTube video teaching electronics for vintage radios. They were highly recommended for both product and service. I needed an Isolation Transformer for working on vintage radios. For my projects I don’t expect to need work than a 3 amp isolation transformer and settled for this 5 amp rated model. It does what it’s supposed to do, it got shipped in a reasonable time, ithas been working just fine, and the price was fair. Not much more to say other than I feel a little safer user this isolation transformer.

Good product but not what i needed

The charger was fine, but i got bad advice wnen i ordered it from someone not in your company. As far as i am concerned,your company was first class.

No Complaints!

I bought this variable transformer for use while working on vintage tube radios. It came highly recommended from a fellow radio restorer and seems to be of good quality and works as it should. Shipping was quick and the price was right… no complaints. Instead of buying from Amazon, I wanted to support and buy from a small business and I've heard that this company provides good service.

AC-AC Power Supply 6V AC @ 1670mA; 2.1 x 5.5mm
6V AC Power Supply

Works great, puts out approximately 7.4 VAC which is probably a combination of build tolerance and my actual outlet voltage being a little higher than average determining this, but worked perfect for my application. These are a little hard to find at this voltage, so was happy getting one here. Shipping was quick, well made product, would buy again.

Great product!

I am very satisfied with the power supply, it works for various applications. I was most impressed by how fast I received it in the mail. I ordered one from Amazon and ended up canceling the order after 3 weeks waiting for them to ship it. You guys are awesome!
