I presume the insulation support is too 'open'.
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'm just getting ready to order an assortment of terminals. I was hoping
to avoid having to fiddle with every wire. Thanks for the suggestion.

and Scratchy
It looks like I have the audio troubleshooting solved. 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.
