Right, Don. That's what I'm trying to replace is the cable from the KIO2 to the KPA100 (or KAT100). I have the Y cable constructed (PC --> K2 --> tuner/amp) but would like to make just a simple cable for when I don't need the computer control (e.g., K2 --> tuner/amp) and don't want all of that extra wire hanging around. Just looking to figure out where to get replacement parts.
I suppose the DB-9 would be a find replacement. I looked at DigiKey a few minutes ago and they have those as well as backshell assemblies. The four-conductor cable only comes in rolls, as far as I can tell, so I might just steal a short length from the Y cable I already made. -john On Thu, Oct 28, 2010 at 9:49 AM, Don Wilhelm <w3...@embarqmail.com> wrote: > John, > > I believe you have the KAT100-2, so you plug the KPA100 ribbon cable into > the KAT100.
