JBL L26 - bad crossover?

[sneakyimp]

Thanks for the responses.

I am nearly certain it's the crossover because on one of the speakers, if I adjust the LPad with a screwdriver, the tweeter cuts in and out. If I jigger it just right, the tweeter comes on full volume. Additionally, I thought I had in fact blown the tweeters at first so I bought a replacement pair on eBay which were "working" and "removed from a pair of JBL L26 speakers".

On the other speaker, I also got the cutting-in-and-out behavior when adjusting the Lpad with a screwdriver. Unfortunately, it's a lot more finicky.

The bottom line is that I have a fairly strong hunch that there's something wrong with the crossover and I have at least one replacement pair of tweeters in my possession should I need a replacement. I don't have an ohm meter or any of the spray to clean the Lpads so I am wondering if it would be cost effective to take it to the local repair guy who's quite close. I know a crossover is not a particular complex circuit so I'm thinking it might be worth it to get that guy to look at it. If I can get them repaired for under $100, I think I'd be happy about that. Otherwise, I might as well buy some Klipsch KG4's for $200-300 or something.

A can of deoxit would certainly be worth the investment particularly considering the money you've already thrown, and are planning to throw, at these.
