former from the high voltage capacitor.

4. Remove one (1) screw holding earth side terminal of

the high voltage rectifier assembly.

21

5. Disconnect high voltage fuse and terminal of high

voltage rectifier assembly from the high voltage ca-
pacitor.

magnetron and remove the air guide.

4. Remove the one (1) screw holding the chassis support

to the magnetron.

5. Carefully remove four (4) screws holding magnetron to

waveguide, when removing the screws hold the mag-
netron to prevent it from falling.

6. Remove the magnetron from the waveguide with care

so the magnetron antenna is not hit by any metal object
around the antenna.

CAUTION: WHEN REPLACING THE MAGNETRON,

BE SURE THE R.F. GASKET IS IN PLACE
AND THE MAGNETRON MOUNTING
SCREWS ARE TIGHTENED SECURELY.

frame, adjust the upper edge and right edge of
the key unit to the correct position of  control
panel frame.

3. Stick the key unit firmly to the control panel

frame by rubbing with a soft cloth so not to
cause scratches.
