Check all the capacitors one at a time for leakage.You might also have a transistor in the preamp stage which is starting to go bad. Whatever you do though don't use the speaker output jacks of the organ as line outs into the input jack of the guitar amp. In a properly working organ you could destroy the output transformer and the input stage of your amp because most speaker outs are A.C. voltage to drive the speakers not low level D.C. which is what your amp is used to. Let me know how you make out.

You may be right! I can get a signal, from both speaker jacks and from the headphone socket, which I then can amplify using a 40W guitar amp. There is a loud background whine which can be reduced with the equaliser knobs on the guitar amp but not eliminated. Mike J
If the preamp board is passing signal to an external amplifier the problem you are having is further along in the circuit not in the preamp board. Maybe I don't understand well enough what your problem is or what you are trying to accomplish.
