I have had one and a fine case they can make.
But the place to start looking is at a chopper that they use in it. Its made
of 2 neon bulbs and two photo cells. With age the neon bulbs die.
What did on a voltmeter that suffered the same issue was use a modern
chopping opamp.
Yup to a bit of doing. O
Try Dave at ArtekMedia.com. He has a huge inventory of scanned HP and Tek
manuals.

Greetings to the List:
Can anyone point me to a source of service literature (schematic, specs)
for an hp 7563A logarithmic voltmeter?
My recent purchase will become a cabinet for a different project if it
can't be brought back to life.
Thanks,
Peter
