brad0112 Posted October 13, 2020 Share Posted October 13, 2020 Hi All - I have come across a local seller with a single La Scala (LS-BB) SN #7P896 with AA crossovers. From a google search, it appears to have been used as an organ speaker, as it has the amplifier mounted inside. The seller is a resale shop (not a fellow enthusiast or stereo dealer) and says it "is not working", but thinks that is due to the amplifier. There is also some damage to the cabinet (see pictures). My intent would be to remove or bypass the amplifier and use this as a center channel with my existing La Scalas. My questions are: Am I correct in assuming the amplifier built-in can be simply bypassed/disconnected? Will the physical damage to the cabinet have an impact on the sound, and would the correct way to repair be using some kind of wood filler? Given the condition and age (looks to be 1976), any thoughts on a fair price? Thanks everyone, always appreciate the feedback! Joel Quote Link to comment Share on other sites More sharing options...
Ceptorman Posted October 13, 2020 Share Posted October 13, 2020 It looks to be in decent shape, those wood pieces missing would be an easy fix. Can you try to power them up, by passing the built in amp and connect your power source? Or are you buying them "as is"? Others will come along and give you a better idea on price, but If everything works, I'd say $500-700. Quote Link to comment Share on other sites More sharing options...
Schu Posted October 14, 2020 Share Posted October 14, 2020 I can't tell what topology those amplifiers are... Quote Link to comment Share on other sites More sharing options...
Panelhead Posted October 14, 2020 Share Posted October 14, 2020 Looks like a pair of RCA bipolar transistors. Since amp is mono, push pull. I would not pay 500 -700 for a single in that shape. But do not need one either. Quote Link to comment Share on other sites More sharing options...
carlthess40 Posted October 14, 2020 Share Posted October 14, 2020 It’s a Alen amp. I had many of themIf it does not work. Just remove the wire at the crossover and hook you receiver thereThe amp is a under rated at 100 watts, solid state amp.

JohnA Posted October 14, 2020 Share Posted October 14, 2020 Yes, you can remove the amp and wire directly to the crossover. But, WOW, doesn't the. 2nd pic look like it was dropped?!?! Is that one side coming loose from the side of the bass horn? 1 Quote Link to comment Share on other sites More sharing options...
Panelhead Posted October 14, 2020 Share Posted October 14, 2020 This may be a part out speaker. Drivers, horns, and crossover. If all working, maybe 500.00. Tweeter, mid, K33, and crossover. Depending on what is installed. And if all three play. It could be a K55 and crossover. Quote Link to comment Share on other sites More sharing options...
PrestonTom Posted October 14, 2020 Share Posted October 14, 2020 There is another angle. The La Scala can make a nice center channel (ditch the amp). Every once in a while folks are looking for singles of heritage models. The damage is fixable and the crossover can have some newer caps put in and the diodes yanked out.

OO1 Posted October 14, 2020 Share Posted October 14, 2020 Looks good to me for a center Lacala , amp can be removed , and wood damages can be repaired easily , a light sanding ---and you're all set , plus being an organ speaker , Drivers should in great shape ------------but you should check the tweeter and midrange drivers for DCR to make sure they are in good condition - Quote Link to comment Share on other sites More sharing options...

I think it might just be worth the risk if I can get for a low enough price. I had planned on sending my existing crossovers in to Crites anyway. Randy - I am not familiar with the term DCR? What am I looking for? Joel 1 Quote Link to comment Share on other sites More sharing options...

Joel DCR is Direct Current Resistance -------with an Ohmmeter , you set it at Ohms and you measure the DCR of the drivers - tweeter is 8 ohms , midrange 16 ohms -woofer 4 ohms -any 0 reading or very low number may indicate a bad component - Quote Link to comment Share on other sites More sharing options...
Marvel Posted October 15, 2020 Share Posted October 15, 2020 Those were sold by Rodgers Organs, not Allen, unless they both did. Carl, do you still have any of those amps you showed back in 2017? Bruce 1 Quote Link to comment Share on other sites More sharing options...

brad0112 Posted October 26, 2020 Author Share Posted October 26, 2020 Thanks everyone for your help! I did buy the speaker. It was in better condition than I had expected. A bit dusty and some paint splatters, but I will try to get those off. I unhooked the internal amp and plugged it into mine and everything works! I'll probably still send in the crossovers and remove the volume controls, but happy with the purchase! 3 Quote Link to comment Share on other sites More sharing options...
