looking for datasheets/information on Varian klystrons

[wkb]

I recently acquired 2 Varian klystrons, one is NOS, the other probably used.  Am having a hard time finding product data on
these two.  So... anyone out here in the possession of an old Varian catalogue or datasheets and willing to help?

The images show the part#

Hello Wilko,

All the info I could find on the VA-287 is that it’s adjustable from 10.7GHz to 13.2GHz and is/was intended for ‘studio transmitter communications’, whatever that means.

I haven’t got any information on the V-55 but it looks a lot like the X-13. May it has the same pin connection but electrically it’s probably different.
The X-13 datasheet can be found on www.tubecollectors.org
