I had to send a 5 hour old radio from the east coast to the west coast for repair. You were lucky, they will not answer my emails. It is a shame, because I believe that Mr. Jue wanted the products to be of quality. They are very difficult to reach by phone, or e-mail. I have had to go back and repair solder joints on their versa tuner 5.
Unit is of very poor quality.
Sales adds sound like a used car dealer. I am very upset with them. Also they need to quit advertising the tuner ratings of the old method of input power. We do not use these ratings today. I think you can assume you get what you pay for.
