Hi, Im sorry to hear ,
WOW 31 years old!
Ok, this one is going to need some basic repair for certain. The electrolytic capacitors need to be checked, and a few power transistors need testing as well to determine which ones need replacing.
Its not an expensive fix by any means and if you have electronic soldering skills and the tools and a multi-meter I can work with you on this.
But if not, it would best to call a local organ repairman in to do this in your home.
It will likely only take him an hour or less to know which part for certain needs to be replaced and if he has one in his stock he can fix that for you right then;-)
In any case, I will stick with you until this is complete.
