Purchased components from XIA Song Electronics http://xiasongdz.global-trade-center.com/.
I am an electronic technician and the components I purchased were defective and the company refuses to refund my money. I have tested the transistors and have found that they are defective. The output power is below specifications and they burn up when powered on for approx 20 seconds. They company representative has told me to use them anyway. This is impossible due to regulations and specifications.
I have contacted them via email numerous times and have had no resolution.
Below is the company, contact and address I filed complaint on:
