I would pick the one with the least amount of dust.

Now don’t throw shade on my dust. These are in my 1974 Klipschorns.

right hand side is the  best , the left hand side is gotta be 50 years old

And believe it or not, the one on left still sounds good in my Klipschorns. I’m going to update one set of these. Leaning towards updating the right hand side set.

I believe you hands down ,  when you keep on using parts they last --  you stop they  deteriorate -

 

-the right hand  AA is 3 caps ---a 13uF ,  and two 2 uF , available from PE ,  the inductor on the top left must be checked in case the screw is magnetic ,  if it is , you must replace it with a non magnetic screw -

Or just build a new set from scratch.  Worked well for my Belle inspired clones.

Tested and confirmed screw is magnetic. Were the screws used during development and testing not magnetic? What is the significance of it being magnetic and why do they need replaced? Thanks

correct , the screws were messed up during production  , they were meant to be non-magnetic -The AA  tweeter circuit   has a 245uH air core inductor with a non-magnetic screw  ,   with a magnetic screw  , the 245 uH bumps to 350 uH -

A steel screw in the middle of a coil changes the MH value from spec. A brass screw which it should have been would not change the coil value. A 304 SS screw will also work though they are very slightly magnetic also. Brass is best. There are a number of these out there and conjecture about why they were used. I have a B&K 885 meter and it clearly shows a different value depending on the screw metal. If I remember right the values Randy quoted are correct.

RandyH000 and Dave A thanks for clarification. I suspected magnetic field causing something not to spec. I will replace with brass.

It's a good thing Klipsch OEM is the only correct solution vs "those other guys."

I’m OK with it.

Even though brass is not magnetic, it is an electrically conductive copper-zinc alloy. To exclude both, plastic screws are the best solution.

I don’t disagree, but apparently not the original design.

There are may different types and lenghts available, one should be the right and can be mounted after the X-overs are rebuild ...ymtc ....
