Hi Chris,
Thank you for the link!
I recently had to find some "grain-of-rice"
lamps to replace those burned
out in the illumination side of an HP 2748B optical paper tape reader.
And? Which
lamp did you use? That device is not too uncommon. So it
would probably good to know. My lamp is still ok. But I don't really use
the machine.
Regards,
Philipp
