Hi gang:

In my last report I described how Ray Calvo's suggestion of using 
Radio Shack P/N 272-1154 lamps worked well for repairing the radio in 
my 1988 90Q.  (The lamps for the liquid crystal display and the 
volume/bass/treble zone of the panel were out.)  However, the color of 
the new bare lamps did not match that of the other lamps which had a 
reddish/amber filter.  To correct it I covered the lamps with silicone 
lamp filters.  The ones I used were for larger T-1 3/4 (0.250 inch/ 6 
mm dia.) lamps, but worked OK.  They are available from Newark 
Electronics, among others, and are made by APM.  I used a red one for 
the controls lamp.  It was a close, but not exact match to the filters 
Wiesbaden used for the lamps on the right hand side of the panel.  
Nonetheless, the difference is negligible at night.  For the liquid 
crystal display, the red filter seemed to attenuate the brightness too 
much for daytime use, so I used an amber filter.  This makes it a 
different color, but not unappealing.  The filter numbers are:

     1813/2-R-5 (Newark 30F781) $0.41
     1813/2-A-2 (Newark 30F794) $0.41

There is a minimum order of $25.00 at Newark.  To fill out the order, you might 
want to order other electronic goodies useful for car repair, such as shrink 
fit, contact cleaner, etc.  Newark's number for ordering a catalog is 
800.298.3133 ext 48.  I have not checked on whether Radio Shack carries lamp 
filters.
