[time-nuts] Volt-nuts cooperation?

I agree that electrolit like to fail, after years of sitting on a shelf.

I have had the 3455 for 6/7 years, and has not given me any problems.  Year
ago, a brand new RF section for an 8568 found me; this has been good, as
well.

Not nearly as good a deal as my $50 including manuals and shipping HP
3457A...  you gotta love sellers that don't check the fuse...

Also one should be very wary of new-in-box vintage equipment.  It tends to
have a much greater failure rate than used equipment!  The major culprit is
bad electrolytic capacitors.  Electrolytic caps that had never really been
powered up and that sat unused for ages tend to fail much more often than
caps that had been powered up for a reasonable amount of time early in their
life (even if they then sat unused for extended periods).

Lucky me, I bought an HP3455A new still in the box for $300!
