La Scala with built-in amp and damage questions

Recommended Posts

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:

 

  1. Am I correct in assuming the amplifier built-in can be simply bypassed/disconnected?
  2. 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?
  3. Given the condition and age (looks to be 1976), any thoughts on a fair price?

 

Thanks everyone, always appreciate the feedback!

Joel

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.

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 -

Thanks everyone!  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?

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 -

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!
