There are two mailing lists that may be of help. One
is
the Agilent-Hewlett-Packard list and the other is the
Boonton list.
http://groups.yahoo.com/group/hp_agilent_equipment/
http://groups.yahoo.com/group/Boonton/
As you know Boonton Radio was bought by -hp- who
continued to make several of the instruments. This is a
very active list. Some of its members started a list
dedicated to Boonton Radio and other equipment made in
Boonton N.J. Not too active but may be of help. I
suggest
posting to both lists, you may be able to find a part.

Richard-
Thanks for the Yahoo groups info. I didn't know about
those two.
I joined the Boonton group as I have a couple of 260A's
both in
need of repair to some degree. Now if I can just find some
time
to work on them...

There are probably a few people on one or the other of
those groups who know the 260A well. At -hp- all the
Boonton stuff was done by a couple of specialists who did
nothing else. I think the 260A is reasonably easy to get
operational, the 250A RX meter was a bear to get calibrated
and the older 160A Q-Meter requires a special tube which was
selected. Boonton liked using selected tubes, one of the
202 series RF generators used three tubes of the same type
but selected for different characteristics. A royal PITA.
There have been a couple of other Q meters made but the
260A is still an excellent instrument. The trouble is that
most people now have no idea of what they do or how to use
one.
