Re: DIY: Repair of HP Step Attenuators
|
There's good older threads that go into some detail on this. I repaired one set a few years ago, posting here, and I recall the "surgery" aspect of the project. Mechanically, maybe one of the more demanding projects in this type of work. I used watch o-rings, but there are more appropriate materials and sources of o-rings for this specific purpose.? I was also able to find a very good video of the procedure on youtube, and I think there are several others available.? Good luck with the project.? Radu.?

I found the little rubber orings have broke.
I need to know exactly how to disconnect the rods that the orings are on from the contact, without breaking anything.
Thank you to ? Microwaveengineer1968??? for an excellent write up.
