    When you may need an isolation transformer

    An isolation transformer can help reduce RF power noise in an electrical system. An isolation transformer is designed to provide electrical isolation between the input and output circuits, typically by using a transformer with a 1:1 ratio. This isolation helps...

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.

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.

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.

Here in central Florida, the lightning capitol of the USA, we get frequent damaging power surges from lightning strikes on the power lines that has damaged electronic equipment. I inserted two isolation transformers to protect my computer and tv. So far no more surge problems.
