I can definitely hear the difference in sound. I couldn't sleep, so I installed them at 0300, that's 3:00am for you civilians They sound less shrilly, and I like the selectable settings of the squawker--I'm still playing around with what suits me. I'm no audiophile, but I feel the ALKs smooth things out. BTW, did I mention how nice looking they are? Quality + workmanship abound--shout out to Al K! PS the AAs on Ebay are SOLD

On Ebay...Upgraded to ALKs got from Q-Man. Now, I'm selling the AAs they replaced. Two Type AA (not matched) balancing networks. Pulled from La Scala SN 4N385 (circa 1975) and SN 7P216 (circa 1976). These DO NOT MATCH! Components differ--same great Klipsch sound. BOTH OPERATIONAL--some repairs have been made; I had to replace a faulty capacitor when I bought the La Scalas. Additionally, I reversed some modifications performed by a previous owner; returned to original configuration. One network has oil-filled capacitors (non-PCB). For reference go to www.klipsch.com and go to forum and search on AA Estimate shipping weight of 14 lbs Buyer pays shipping from Zip 22192 Phone me for questions. TC 703-589-7041

SUCCESS! Thanks to everyone's input and recommendations. Followed DJK's advice: step by step T-shooting. Just like the man said, "at some point the tweeter will sound." Result: open 2uF capacitor adjacent (schematically) to the 13uF cap. R/R with Radio Shack metallic/poly (2) 1uF in parallel (temporary.) Will save my $$ for an ALK. Thanks to all--livin' the dream. tc

Okay. Returned both crossover AA bal. networks to stock config (thanks to Steve Phillips and DJK for schematics.) Orig fault still exists: mid and woofer working, one tweeter inop, however it is not defective because I swapped it. - Resoldered all joints I'm still lost. I'm thinking it's either the two caps or the coil--what's left? How do I check with just a V-Ohm-Meter? Any help,

Thanks to DJK for locating an AA schematic.

Hey folks! Just acquired a pair of La Scalas SNs: 4N385 & 7P216; the 4N385 won't drive the tweeter--mid and woofer working. It's not the driver; swaptronics came in handy. Also, the pair has had an aftermarket mod in the way of some potentiometers rigged in the ckt. HOW SHOULD I PROCEED T-SHOOTING? Thanks in advance, tc
