It might be best to just put 1/2-1" piece of heatshrink over the 22AWG to build it up. When the famous Red/Blu_T-head Tool by AMP was king of the toolbox, nylon over pvc was the popular airframe wire . . . fortunately, the insulation grip cam had one more down-size notch on the cam so it works good for Tefzel. It won't grab a Kynar wire . . .

I was hoping to avoid having to fiddle with every wire. Thanks for the suggestion. do not archive Raymond Julian Kettle River, MN.

I replaced the amplifier chips because I had some extras locally and they are cheap. Then I tested the intercom input by connecting my mp3 player directly to the intercom, bypassing the 9009 all together. All was well. Next I removed all of the inputs to the 9009 except the music, and plugged it in. All was well. Next I connected the Dynon voice circuit. It was acceptable, but a little bit loud. I took out the 300 ohm resistor for that channel and tried a 500. The change was small, so I swapped a few more times, arriving eventually at 1.8k. This really surprised me, since I misunderstood and thought of 300 to be near the top end of the scale. Next I reconnected the 430 nav audio to the 9009 and it was way too loud. I jumped right to the 1k, but it was still very loud. After several steps along the way, each astonishingly higher, I settled on 68k. Now everything works well and the chips aren't getting hot. I mention all of this for the benefit of anyone else who will be using the 9009 with these systems- start much higher than 150 ohms! This whole process has given me much more understanding of my audio system, and also a real appreciation for the design of the 9009. Thanks Bob for making it available! I don't know how other folks are getting by without it. On Apr 10, 2013, at 18:21, "Robert L.
