Bad Power Supply / AC Adapter

I understand what you are saying. I have 2 of the 2-tuner Table units. Both have the original power supplies made by Adapter Tech. Interestingly enough, one has a 2 amp power supply, the other has a 1 amp power supply, but both have worked flawlessly for a couple of years or more. I do have a small USB cooling fan that blows on both units continuously, maybe that helps.
