You might want send a PM to chicagobill who is a tech and a meneber of this site, as he is not that far from you.
You might also try finding a electronics repair shop near you who has someone on staff like me or bill who is in the 50 year old age range and grew up fixing these type amp circuits 30+ years ago.
It seems a lot of the so called techs these days, are just board changers as that is the way you fix new stuff since its all micro circuits and can not be worked on.
