HP8558/9 Nylon Clutch


 

Hello All, my first post :-)

I have been searching the group history for any information about a possible source for the Nylon Clutch mechanism that is part of the input attenuator/reference level switch on the above analysers.
I don't have the part number to hand but I could find it.
No success so far.

It seems a particular weakness of these otherwise excellent analysers.

I have an 8558 with the Atten switch completely useless (has been in pieces for years for want of these parts) and an 8559 that is going the same way.

Is robbing parts from another unit the only option?
I don't suppose a 3D printer (a very good one!) might be any solution?

Regards Jon
