Replacement of magnetron (V1/V201)
Remove the shield cover of the modulator and check that no charge remains in the high-voltage modulator
circuit. Then, remove the socket of the magnetron. The magnetron can be demounted by removing the
screws fixing it. When mounting a new magnetron, do not touch the magnet with a screwdriver or put it on an
iron plate. After replacement, connect the lead wire correctly.
Handling of Magnetron under Long-Time Storage
The magnetron that has been kept in storage for a long time may cause sparks and operate unstably when its
operation is started. Perform the aging in the following procedures:
(1) Warm up the cathode for a longer time than usually. (20 to 30 minutes in the STBY state.)
(2) Start the operation from the short pulse range and shift it gradually to the longer pulse ranges. If the
operation becomes unstable during this process, return it to the standby mode immediately. Keep the
state for 5 to 10 minutes until the operation is restarted.
