Query: Excellent Quality Transformer - Highly Recommended.

I am very happy with AVEL Toroidal transformer. Its a Good Quality product and I did research on the AVEL and they make Quality transformers. AVELs Customer Service was Great, I called them with the Question on color wiring mismatches and the lady on the phone was very polite and was able to clarify it. Product is built solid, nicely insulated. Good guage wires and comes with mounting accessories.I am planning to use this transformer on custom built - TA2022 Tripath Amplifier. Please select the right voltage, VA and 22-0-22 vs 0-22v, 115v vs 250VAC. It will save you a return.
