I have a Kenwood Vr 510 and decided to upgrade my Remote to a new Harmony one and guess what the Receiver is RF controlled and to upgrade to a IR 9991 is 220 US I have checked on some old sites and saw that a few people weere talking about using a Xantech 291 -10 IR Transmiter but that is as far as the threads went Did they work Has anyone else done anything to make these Kenwoods work My concern is that the Voltage of the Xantech is diffrent and one thread talked about this but there was no repsonse as to if it worked etc. Any help would be appreciated.
