500VA Isolation Transformer, 117VAC to 117VAC

Needed for bench work on some older type tube receivers. Fit my needs also the two outlets provided a plus. Received quickly and well packed. Completive pricing
and reasonable shipping would use again.

There are no guarantees that a transformer will cure any noise issue, and this did not. Also, because it hums, it is introducing noise into the room. I did not expect this. I am debating on whether to return it, redeploy to another area, or to upgrade to a balanced power solution, etc. It has serious heft, so I am sure its a good isolation transformer. I feel like it may have opened up/uncompressed the low end quite a bit, but can not measure this accurately.

It did a good job as advertised. I was getting a hum when I turned on my subwoofer. I plugged the sub directly to the isolation transformer. It decreased it by about 90%. Maybe if I plug my sub into my power conditioner and then plug the power conditioner into the transformer it might eliminate the hum completely. I have not tried it yet. Have not had time,but the hum is barely noticeable now. I have to get very close to the sub to detect it. Very happy even with the 90% hum reduction
I'll will definitately keep it
Great product..

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.

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.
