As promised, I'm reporting back...
Let me just say: "Don't try this at home, kids"
Hooo boy what a project! Getting it all apart isn't bad, but
I'd say that this was probably the single toughest soldering
job I've EVER done in my life. I have a very good iron, with a
very long pencil point tip iron that is practically a needle,
so I have the equipment. I tried using some strands of
solid copper from CAT5/Cat6 cable.
It took me many many tries to be able to get in there with a
reliable connection of the wire to the solder pad without
getting near the top silver holdown switch top. Every time
I missed I had to clean it all back up again. Once I got
the wires hooked to the switch, I got the capacitor
soldered in to the wires. Then I assembled it.
..and assembled it, and assembled it. There are many many
steps to getting everything lined up just right so that you
can successfully reassemble things. I forgot the screws
a couple times, didn't line up the wires under the battery
area a couple times. Had both my black and red battery
wires break off the board once, and when I did finally
get it all back together, the external button action wasn't
perfect anymore. This is because now the button doesn't
just push in on the switch anymore, it bottoms out on the
hook-up wire that's near the switch. So, it doesn't make
that nice "click" when you hit it. To make matters worse,
when I put batteries in it and tested it, it would turn on,
stay for about 1 second, and then turn off. I can't for
the life of me see where/how I actually did anything
that caused harm when all was said and done, but it just
plain was so micro-scale that without a very good large
magnifying lens you just plain won't even see the defect
or see to do the job. The task requires something good
to hold the board steady, a good light, and a good
magnifying lens.
So, after messing with ONE of the headsets for at least
2 or more hours, and seeing what happened, I ended up
taking it apart AGAIN and removing all of the stuff,
and doing like 3 more reassembly sessions to get it all
together, and then yes, it still didn't work properly.
So today, I sent it back and they are sending me
a new one.
While I applaud Matt for figuring it out, and showing
how to do it, I personally just can't recommend that
someone do it themselves. If Matt will do it for $100,
that is a real bargain. I spent hours at it, and most
likely was the cause of the damage. I'd be tempted
to try again, knowing all that I know now and
using that to be even more diligent, but my wife who
was right there helping was also saying..."wow,
I don't know if this is worth it..." Had the button
action been perfect, I'd probably try it again. I'm
pretty good with small soldering things, but this one
kind of kicked my butt.

We had a similar experience with the Belkin Bluetooth receiver. I ordered the first one (clue?) and saw the 12V cigarette adapter and thought ahhhh this should be easy to hard wire into the ships power. <<SNIP>> only to discover that there are lots of electronics & brains in the power adapter. No way to get the unit to work after the "big cut". There was a simple solution though. Whip out the still warm credit card and order a second unit for $90.00 and integrate a female power receiver instead. The bulky adapter and extra cable is hidden in a vertical support structure out of sight. My new policy is to only modify what I can willingly afford to replace.

Matt, you rock! That's awesome that you found a way to do
this. I'll definitely be taking at least one of mine
apart and trying this. If it goes well, I'll do 'em all.
It's the single thing I wish they had a dip switch for
that you could enable, and you got the answer. Thanks
for the great write-up.

Dear Listers,
I bought a couple pairs of the new Bose A20's for the RV-8 and they
are very nice. NR is better than the Bose X's and they seem to fit
my head a little better too.
But I quickly discovered that with the A20's you now have to hit the
NR Power button *every time* you start the aircraft even if you have
them panel powered. The older Bose X headsets have a slide switch for
the NR power and so you can just put the slide switch in the On
position and not worry about it.
I really didn't like having to turn the NR on all the time and having
to remind my passengers about it, so I came up with a modification
that will automatically turn the NR on when panel power is applied.
Its pretty simple, but requires some special tools. Its completely
self-contained inside the Control Module and works great. The
modification is generally only for installations that are
panel-powered, but you could do the modification to a unit that is
normally battery powered with no adverse effect. With the
modification, the NR Power button will work normally in battery power
installations.
I created web page on the procedure including step-by-step photos and
instructions. Feedback is welcome.

Wow, Tim, that was quite an ordeal...  Sorry to hear you had so many issues.
Both of my buttons still have that "click" feel after the update. You might have gotten those little metal ears too hot and melted the internals of the push button.
Did you use insulated wire for the connections between the switch and the capacitor? That blue wirewrap wire I used is insulated. The Shack has little spools of it. Perfect for this kind of stuff.
I bet the second time through you could do it perfectly. The second one I did I think I did in 15 minutes. The first one took a lot longer, though.
My $100 offer is always available.
