IF power supply died, why does everything except the keyboard function
properly?

It sounds as though the power supply has died!

Hi,



I'm a new member to this group and am in need of assistance.  



I have a 1973 Mini-Moog that I put in storage about 10 years ago in my attic
in the original case. At that time, it was working fine.  [Attic is
insulated and doesn't change temperatures too extremes - maybe 50 degrees in
winter and 90-95 in summer]



I recently took it out, turned it on and noted that the keyboard doesn't
work...Keyboard will trigger the oscillators, envelopes and the rest fine,
only won't change notes...Single note sounds throughout the keyboard
compass.  



Pitch bend works fine but no note change with the keyboard, only single note
will sound.  This seems to be the only problem.



I did leave it on for a few days and took the circuit boards out, applied
DeoxIT on the contacts and reinstalled them to see if there was some type of
corrosion had developed but to no avail. 



I'm not all that technically experienced and don't have a service manual so
I have no idea where to start, asides form cleaning the board contacts. 



I live in upstate NY, near Saratoga Springs and can't find a service tech
nearby to take it to.  



Any suggestions? 



Thanks
