Crossover suggestion for Infinity Servostatik

I suspect that the high channels of my Servostatik crossover are going out.  Mid and bass seem fine.

I'm looking for a 3 way stereo crossover that I can use to bypass the high and mid channels for diagnosis.  Does anyone have a good recommendation?

It doesn't have to be fancy, just something for diagnosis and temporary use until I can get it fixed.  Even a car audio version would be ok.  I can look up the frequencies required if it will help.

Thanks, Mark
Wow, SS ones? I use a DBX crossover with my Infinity RS1Bs. They make a stereo 3 way crossover but you might have to use adapters for the XLR connectors. Should do the job. You can toss the internal crossovers and just run the DBX. Affordable but it sounds great. But you'll need to be tri-amped I think? 
Man, take your question over to DIYaudio where you will be much better served on crossover diagnosis.
