   just finished up. The sound is very tinny. like it's out of phase or   
   something. Like very high distorted treble. I tried different speakers with no   
   change. Replaced the needle    
   with a new good Shure. What are your thoughts on the cartridge being bad? It's   
   wired correctly. If that's not the problem then the amp is going to need   
   re-built. Your thoughts? Thanks!

   out of phase like AMIs - when you say the cartridge is wired correctly, is   
   that as per diagram?

   Rock-Ola it's not wired out of phase as per the manual instructions. The amp   
   needed re-built. It's all back together and sounds good now. Not as good as my   
   AMI but as good as a    
   Rock-Ola.

   the 12 inch loudspeakers sum the two output channels as per AMI.  It's the   
   same amp (54510-A) that's used, strange that Rock-Ola should change back.  I   
   must confess I don't    
   have a 494 manual though.   
      
   This box came with all the papers. Even the inspectors check list before it   
   left the factory. When I was having sound problems I compared it to my AMI and   
   thought I'd found the problem. Then I looked in the manual to double check and   
   saw it was wired    
   correctly not like the AMI. After the amp re-build it sounds good but my AMI   
   sounds so much better.
