Has anyone come up with more modern replacements for
the voltage regulators in the HP8660a? I have one
that has 0v on all but one of the regulated lines,
so will have to dig into it, but the part numbers
don't seem to have cross references with generic
devices.

I also understand that later models such as the 8660c
use basically the same power supply but with different
(hopefully more reliable) components. Anyone had
any experience with substitutions in this area?


Any suggestions would be greatly appreciated.

cheers, Paul
