Bert-
I would be willing to take a chance on a used tube if the price was
right.
Please keep me in mind as I have been looking for a used Cs tube.

Hi,
let me start out with a disclaimer, I have sold several HP 5061A
through a
friend on ebay including the two recent HP 5062C's, the reason I do
not do
it direct is, he does it full time and he has the ability to get them
packed professional. We have had no complaints all where tested and
with the
exception of the 5062C sold as fully funtional and till now there
have been no
complaints. Two more will be sold and are the best, kept till last.
I would stay away from any C standard that has not been tested and
even
tested, it is a gamble because the question is how much life is left
in the
tube. I am sure there a members out there that have units with bad
tubes.
I am downsizing because I want to move to a smaller house and am now
down
to a modified 5062C with a FTS tube and a 5061B with a FTS tube.
I have extra FTS tubes and did test them all and I know which are
the best
but I cannot tell what the expected life under normal continuos
operation
will be. I have tested beam current and will set up a standard test
using
21.41 KHz and 2500 Volt electron multiplier.
Maybe there is someone out there that has a correlation between beam
current and expected life I know the end point and I know what you
can see with
a new tube but is there a curve that tells you what you can expect
life
wise?
Right now I am only prepared to sell the two remaining working HP
5061A,
maybe later the 5061B and after more testing some tubes. Any one
interested
please contact me directly.
