runninshine Posted July 20, 2013 Share Posted July 20, 2013 I bought a pair of beat up La Scalas from a guy who had one in his garage and the other on his front porch. He said he modified the network so it played in stereo when hooked up. I would like to do the same thing but I am not sure if this is correct. Take a look at the network and let me know if this will work. Thanks. [Y] Quote Link to comment Share on other sites More sharing options...

Deang Posted July 21, 2013 Share Posted July 21, 2013 It looks like the low pass coil and woofer have been disconnected. Those LaScalas may be more beat up than you think. Quote Link to comment Share on other sites More sharing options...
Coytee Posted July 21, 2013 Share Posted July 21, 2013 He said he modified the network so it played in stereo when hooked up. Isn't that what the second speaker is for? I don't know anything about the lose wire but it sounds like that guy had a wire loose in his cranial network Quote Link to comment Share on other sites More sharing options...

Guest David H Posted July 21, 2013 Share Posted July 21, 2013 Here is the AA schematic, I recommend putting back to stock. Dave Quote Link to comment Share on other sites More sharing options...
runninshine Posted July 21, 2013 Author Share Posted July 21, 2013 I spoke with the seller this morning and I did misunderstand him. He said he altered the network because he was just listening to the one and wanted to play it in mono just using either the right or left side of the amp. He said he couldn't remember how he did it but used a diagram from this website. [^o)] I just put in an older AA that I had around and both speakers sound fine, they just need a little finish work.

seti Posted July 21, 2013 Share Posted July 21, 2013 Weird. Wouldn't it be easier to mute a channel. Quote Link to comment Share on other sites More sharing options...
Rhetor Posted July 24, 2013 Share Posted July 24, 2013 I just put in an older AA that I had around and both speakers sound fine, they just need a little finish work. How can they be older than the AA in the pic? [^o)]. Glad you got them working. How about some pics of the now working La Scalas? Quote Link to comment Share on other sites More sharing options...

What does listening monaural through one speaker have to do with modifying the crossover network for that one speaker? You need to sum the stereo signals much further back in the chain. babadono Quote Link to comment Share on other sites More sharing options...

How can they be older than the AA in the pic? . Glad you got them working. How about some pics of the now working La Scalas? Those look a bit more modern than the AAs that came in my 1974 La Scalas. Those ones had stacks of caps to add up to the correct values, two stacks of two and one stack of three. I replaced them with Sonicaps from Bob Crites, which sounded better, and left lots of space on the crossover board. Quote Link to comment Share on other sites More sharing options...
