Did anyone ever replace the lamps of the keyboard switches?
It seems that I need to open the keyboard for that. (Or can it be done
in another way?)

I replaced mine ages ago, I think the switch caps can be pulled off revealing the bulbs which I got from Maplin in the UK (unlikely to have them now).but Farnell have some that look right. They should be avaiable as the lamp is the type that used to be popular in high end telecoms equipment.

Hi peter,

There is a thread from long ago in this forum that even had pictures.
Scan for 'lamp' or 'bulb'.

Also, you might be able to replace the lamps with white LEDs and a
resistor. If you carefully remove the bulb part and insert the LED instead
you have the correct fitting. So don't throuw away the lamp just yet.


Good luck,
Harald.
