Is this a Multi-tap resistor in an older N1200 crossover?

[Eric M.]

I have not yet taken this N1200 crossover apart, so, am unable to put a meter on this component but wanted to make sure it is what I think it is!

It looks like 2 separate resistor windings, one which is tapped somewhere in the middle. I do recall finding a wire wound resistor with a center terminal on a N1200 years ago, would this be the same thing just an earlier version?

Before I get too carried away and try to build a replica out of fixed value, non-inductive resistors, can anyone think of a reason why that would not work?
I'd hate to end up putting this on the shelf next to my failed air core autoformer experiment.

Thanks,

Eric

No One??

I know that Altec used ( for many decades ) one ( or 2 ) multi-tap resistors to create ad-hoc L-Pads (sometimes using the same rotary-switching method as shown in your pics ).

Your pics are quite unique. I've never seen a pic like yours ( with parts like those inside a JBL N1200 crossover ).

I think you may have solved it. They sort of look the same.
I'm going to take this one apart assuming this is a multi-tapped resistor and draw up a schematic.

Once that is done I'll post and we can see if that makes sense.

Thanks,
