Hello, My apologies for the intrusion. but I have a question that I
am
hoping someone has an answer to. I have never posted to a news
group,
so again, my apologies if this does not meet the standard protocol.

I have a bunch of Raytheon Subminiature tubes that I inherited from
my
Father, who was an electronics bugg (I followed a different path)
that
have code QF-721. In searching the internet I have found a bunch of
identical looking tubes such as one labeled CK6088. I have done lots
of searches on the internet and I cannot find out anything about
these
and am wondering if you know about these, or if you can point me to a
website that might shed some light on these.

I am considering the possibility of donating these to someone but if
I
cannot find out what they are for, I cannot imagine how I can find
who
to donate them to -- perhaps a school or something.
