I just acquired a custom built Altec Lansing 803b/804a set of speakers. They have custom made crossover. Just would like to get some expert opinion on it.
Is this crossover any good? Should I rebuild it? or build a new set. I tested the speakers with Dynaco Mark III mono amps, and they sound wonderful. Thanks.

Download a frequency response app like Decibel X on your phone and measure the drivers by themselves, you know, just the woofers and just the tweeters but through the crossover. See if the woofer is rolling off and the tweeter turning on at the same frequency, which is probably 800 cycles. If so and you like the sound you're good.
 
NO! Those are vintage oil caps and have their own sound. I've tested similar and always found them to be right on the money. They also probably used air core inductors, which are superior to ferrite core.
