Hi Guys,

I managed to get her booting again and play the sounds. =)

My instinct was telling me that it must have been related to the 
reseating of the digital board ICs because it was working prior to my 
chip cleaning.  So I removed and reseated them 
all and... voila!! 

However, the same voice problem on channel 7 still persists.  I also 
tried to swap IC31 and IC55. No difference.

Does anyone know what else it could be? It seems like I swapped all 
relevant chips on channel 7 with no results...

Thanks.

George
