[time-nuts] HP-5065A Rubidium Standard end of life query

[Bill Hawkins]

Have a 5065A with a RVFR that says the warranty ended in 1988.

Bought it from eBay in 2003, had a 1998 cal sticker.

Photo current is below normal, second harmonic is 9, but it works.
Been through the manual, ran an amp through the RVFR for five days
until the second harmonic improved, back in 2008.

Google is no help when looking for an RVFR package. Thinking about
using an LPRO to maintain the function within the classic HP package.

Is anyone else still using a 5065A?

Can the RVFR be replaced?
