Hi thanks. You dont need the remove the wires , there is enough cable lenght to work , i did it to clean the boards ,  the boards was completely covered with a strange brown goopy stuff , was in a barn for 20yrs so , no wonder ! 

pwm is repaired , forgot to wire the pwm vco output .. hihihi 

tonight is the silent voice repair time .. this one is more uncertain ,, VCA perhaps ,,,,. 

next time !

I'll just have to go real slow but your story is really very inspiring.
