96lt1ss Posted August 25, 2019 Share Posted August 25, 2019 Have an older pair of La Scala’s with AA crossovers and looking to find out if these need any maintenance or capacitors replaced as they get older. Also heard these run warmer than others so is there a recommendation for that or is it just a characteristic of them. How owe do I determine what year they are?

96lt1ss Posted August 26, 2019 Author Share Posted August 26, 2019 Do they make a capacitor refresh kit for the AA crossover? Quote Link to comment Share on other sites More sharing options...
avguytx Posted August 26, 2019 Share Posted August 26, 2019 Yes, Bob Crites sells a basic capacitor kit on his website which will save you money if you do it yourself. Otherwise, you can send them to him and he will do it...for a fee plus shipping. There are lots of capacitors out there you can use and those crossovers are very easy to work with.

geoff. Posted August 26, 2019 Share Posted August 26, 2019 Hey, take a look at the wire connections on your K-55V’s... Are they soldered on or do the wires go into spring-loaded push terminals? You may have a pair of the golden child’s of LaScalas! What exactly were you referencing by “these run warmer than others”? Nice entry to the forum! BTW ...more pictures... lol Quote Link to comment Share on other sites More sharing options...
JohnA Posted August 26, 2019 Share Posted August 26, 2019 1981 La Scalas are the optimum version, IMO, because they came with 2-piece phase plugs in the squawker drivers, denoted by soldered terminals with a 1981 production date as well as the improved -M tweeter. The newest La Scalas with the new crossover and tweeter might best yours/mine. The latest K-55-X drivers also have soldered terminals, but also modern production dates. If your La Scalas have a polite, reserved, perhaps gentle sound you probably need to replace the capacitors. Use film and foil caps and expect to pay a nice sum for them; they will be worth it. I used Musicaps 20 years (!!!) ago. They seem pretty hard to find now days. While you're in there, consider wrapping the squawker horn with Dynamat or rope caulk to kill the vibrations that remain after they are mounted. Then, stuff the top cabinet tightly with polyester fiberfil (pillow stuffing from Wal-Mart). Rap on the cabinet top with your knuckles to see why. Another good, easy mod is to line the cabinet opening for both the squawker and tweeter with 3/4" felt, covering the plywood edge plys. That reduces unwanted reflections from the openings. After that, it you think you have a midrange glare/harshness, and your room is not highly reflective, come back and ask; we have lots of other easy mods for that. 1 Quote Link to comment Share on other sites More sharing options...

The K-55-X is the same as the old K-55-V push pin with the single phase plug. 1 Quote Link to comment Share on other sites More sharing options...
