[Test-Equipment] Wanted: HP8640B - alive or dead

[Tod - MN]

I am interested in repairing an HP8640B that I have or acquiring a
non-functional (or functional for that matter) one of similar vintage that I
could merge with the existing unit to create at least one good unit.

I am particularly interested in the rotary switch which is located to the
rear of the RF attenuator and just ahead of the RF vernier potentiometer.

Please contact me off the reflector at the following email address:

Thanks, 

Tod
