RE: Those D*mn Little Bulbs!!!
I looked around to see if I still had the file; unfortunately I didn't.
Also, unfortunately, my memory is terrible, but this is what I remember.
Once the radio is out (remember to deprogram it, or make sure you have the
the radio code, depending on the vintage of the Weisbaden unit you have)
pull off the volume/balance knobs and (if I remember) the bass/treble knobs.
Next, unscrew the brackets at each end of the radio. Now, the plastic
nosepiece comes off; pry around the edges and pull the radio nosepiece
towards you until you can pull it off (recommend starting at one end and
working your way around the circumference). You should see the little
"tongues" on the nosepiece sticking into the case slots.
With the nosepiece off, you should see the screws that hold the LCD display
to the metal case; unscrew them and you should see the little bulb behind
Biggest problem I ran into was the length of the wires running to the bulb;
there is NOT much slack. Cut off the wires as close to the bulb as possible.
I used a Radio S**t bulb that goes into a PC board; part no. 272-1154
(however, Hans-J Tannenberger mentioned part no. 272-1092B as a very
Screw the faceplate back on and clip the nosepiece back in place. CAUTION -
DON'T pinch any of the wires going to the bulb; the nosepiece can easily do
this and possibly cause a short.
Note: why change the radio; you'll just block out the radar detector and
the CB radio (NEEDED for ground flying)!

This is the radio station LCD display. Ray, I know you've been here
before. I searched my personal archives (all digests since #477, 20 MB!)
but I could only find messages about the broken circuit board. :^(
Can you (or anyone else) share some more of your micro-bulb wisdom?
What I'm looking for is a bulb P/N, gotcha's to look out for, etc.
