Re: 7904 Switch Lamps
From what I remember reading about those 'aged and selected' bulbs thattoggle quoted messageShow quoted text
Tektronix used, they were selected for light output. I do not think that
those long life (50 000 hours) light bulbs are risk, even used, as far as
their life is concerned, because they are grossly underrated. There is
probably a risk of damaging a bulb in the process of removal, since lot of
them are with wire leads, instead of sockets.

Hi Jay,mainframe horizontal mode switch.
a generic number of 17AS15 for these bulbs. Both numbers are rated at 5
Volts and 115 mA.
they are selected for. My guess is that they are matched for light output.
in the U.S. who will sell small quantities of these. They were used in a
LOT of Tek instruments and your best bet may be to pull some out of a
salvaged instrument. I know it is not the best idea to use used
incandescent bulbs, but these are specified to have a life of 50,000 hours
and I suspect the ones in the "A Dlyd" and "B Int" positions do not have
many hours on them . . .
