3 way crossover suggestion for Infinity ServoStatik

It sounds to me like the crossover on my ServoStatik system is having some issues. The high and/or mid channels are "bleeding" the left and right signals back and forth. I believe the crossover points are 100 & 2000 hz.

I would love to find an inexpensive crossover that I can use to prove this. Presumably I would need to run it for awhile until I can get the Infinity unit to the shop. Even an auto version would be acceptable - maybe even better since it would be easier to hide.

Does anyone have a good recommendation for a 3 way crossover? A unit that can handle both channels would be ideal, but single 3 way is fine if it's not too expensive... I can just buy two of them.

Thanks!

As it turns out, the high end was flaking out and finally died completely. Presumably it's the transformer.


Luckily I have a spare panel with the high end still working so I should be able to swap parts over until it is good as new.
