Re: Tips on repairing the stick attenuator in the HP86603A
|
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?
Thanks!
