JohnA Posted May 20, 2000 Share Posted May 20, 2000 I bought another pair of La Scalas for rear channels. They are '87 models, I think with Type AL xovers. One is fine. The other one has good drivers, but no sound comes from the squawker and tweeter, if you use the input terminals. Nothing is obviously wrong. This is the xover I never could quite sketch correctly. Does anybody have any ideas about what may be wrong? Do you have a schematic of a Type AL? John Quote Link to comment Share on other sites More sharing options...
WMcD Posted May 20, 2000 Share Posted May 20, 2000 Well, we've had reports of a bad connection at the autotransformer. You might check that. Gil 1 Quote Link to comment Share on other sites More sharing options...

JohnA Posted May 21, 2000 Author Share Posted May 21, 2000 I found the problem! It was a loose wire from the + input terminal to an 8 uF capacitor. It was supposed to be clamped and soldered, but the red wire has never seen solder. I'd still like to get a copy of the Type AL schematic. This thing is needlessly complex. drobo sent me a copy of Types A, AA, and AL-3. I think the AL-3 may be the direction to go. Maybe I should have said "stole" rather than bought. I expected far worse problems. John Quote Link to comment Share on other sites More sharing options...

JohnA Posted May 21, 2000 Author Share Posted May 21, 2000 DDick, You're right. I've already thought of that, but we need more info to see how the K-55-M is different from the -V Al designed for. BTW, I got them installed and calibrated this afternoon. The difference between these La Scalas and my old Bostons in the rear is really noticible. Better clarity and from the rear corners, plenty of dispersion for Pro-Logic. Rears matter. Size matters. We watched "The Sixth Sense"; spooky. Now I get to go upstairs and scare the living *&*& out of Cathy. :0 John Quote Link to comment Share on other sites More sharing options...
