Hi All!
Dont ask why, but I am resurrecting several HP
8660D generators with the HP86603A plugin. The attenuators
are "sticky", get stuck in a certain position. If you have
experience with this exact type of stick attenuator (long
silver block) with the 3 - 40 dB, 20 dB, & 10 dB
sections and can advise how to make a reliable repair, I
would love to hear about it. Several that I cleaned the
solenoid shafts on seemed to be working only to stick
again. I do not know how to search the archives as well,
can someone advise?
Sounds like the universal problem of decaying O-rings Jeff.? They
are easier to replace than source.
