## Description

desertcart.com: Prem Magnetics EI-14 Audio Transformer, 5 pcs/Pack, 1K:8 Ohm Impedance, Isolation Output XFMR : Electronics

Review: Worked great for my application - I needed an 8:1k Ohm transformer and this is the only one I could find that wouldn't take a month to arrive. Every one of them worked without issue. I needed them to make a laser communicator for a class project and they worked perfectly for this application. I can't speak for the long term reliability as I did not use them for long, but out of the box they worked perfectly for me.
Review: Wrong information - The size and color are different from the advertised transformer. I even got a reply back from the seller assuring me the advertised dimensions are correct. After receiving the product it was obvious the product is "NOT AS ADVERTISED". Advertised: Item Dimensions LxWxH 5 x 3 x 4 inches, Actual is about 0.6 x 0.6 x0.4 inches. So don't trust any answers from the seller. From seller:" That is the size of each transformer. regards, "
