Jeff is a prince, an absolute Prince, I bought an OS from a forum member who bought it from another forum member who bought it from JTR. Right after I hooked up the OS the Prot red light began flashing 4 times then repeating the 4 blink series. I called Speaker Power to find out what the 4 flashes meant and was told I would have to send it in. I called JTR and Jeff picked up the phone, what a treat, seriously, how often do you call the factory and the Man picks up the phone. Jeff said send it to SP, I did, SP fixed it and JTR picked up the tab, including return shipping to me, very impressed. Oh, and by the way, the OS is awesome, very impressed. Life is good with really good base.
