NOTE.... Test the voltage on your AC Adapter, if it is much over 14.9V then don't use it. I could shorten the life of your BT Receiver
UPDATE ----- Nov 25 2018
Here are links to the 3 Bluetooth Receivers that I use and recommend. These units are not cheap but will give you many years of service.
1) Fusion BT100... https://amzn.to/2TMUoKq
2) JL MBT RX.... https://amzn.to/2DXEsAq
3) Harman Kardon BTA 10 (My pick).... https://amzn.to/2KvYO4r
4) This 12v Wall Wart 110-12v Adapter will work well. https://amzn.to/2I6Jh8O
