As the subject says, I would like to add a low level remote control to my amp. Amp is Phoenix Gold Xenon 400 x 1 mono. I found the part I need, LPL-44, but it is either discontinued, or $35 bucks shipped from all online retailers.

My question: They all look about the same (low level remote controls), they plug into the amp w/ phone like jack (not sure if width of phone jack, or ethernet, I think phone) and thats all there is to it. Assuming I find one that looks the same, is there any reason this wouldn't work?

Any specific, cheap, controls any of you have used or recommend? Thanks
