Greetings:

Sorry for the off-topic post.

PLEASE, SEND ANY REPLIES _DIRECTLY_ TO ME AND NOT VIA THE REFLECTOR.

I have a DOA Motorola Amplified Speaker, model SSN2005A, PC board 
nomanclature is SLN4244A.

I also have a working SSN2005B/SLN4244B which is virtually identical to the 
DOA unit. I was gonna do some voltage comparisons, but the problem is that 
both boards are SMD and it's almost impossible to do signal path tracing... 
esp. when I have no clue about the ICs and where they fit into the circuit.

If you have access to a schematic for EITHER of these PC board designs, and 
might be able to provide a schematic (hard copy or a scanned image, even if 
in pieces) I'd really appreciate it. I'd pay for copying if scanning is not 
an option.

I have some printed literature, for rewiring the speaker, which tends to 
imply that models TLN2660A, TLN2661B, and SSN2008A "might" be similar, but 
I have nothing else to confirm or deny this assertion.

ANY assistance would be greatly appreciated.
