WARNING
Hazardous voltages are present in power sup¬
ply circuit. Disconnect AC supply cord prior
to disassembly. Exercise care when making
tuning adjustments with unit operating to
avoid contact with exposed wiring near pri¬
mary switch and fuse holder.

DISASSEMBLY PROCEDURE
NOTE
Before proceding with disassembly, take care
to protect finished wood and lacquered metal
parts from sharp objects. Use carpeted or
similarly protected surface.
To gain access to tuning adjustments, bottom
assembly including keyboard must be separated from
upper housing. Start by removing (2) screws from
lower rear panel located on either side of Moog logo.
Place unit upside down and remove (4) screws
holding bottom to wood ends. Remove rear key¬
board mounting screws near center of bottom and
loosen (3) front keyboard machine screws until they
are finger tight.
Place unit on its feet, lift rear edge approxi¬
mately one inch and tilt forward to release housing
from front groove.
Slide housing forward to clear keys. Lift and
rotate front of housing up and rest on rear panel. Take
care not to stress flexible "tails" on membrane switch
which connect this panel to a P.C. Board at rear of
unit.
