Which of the following is NOT a precaution that should be taken to ensure the magnetron is not weakened?

Magnetrons are sensitive to thermal and mechanical stress as well as stray conductive objects nearby. Excessive heat can wear out the tube’s cathode and reduce life, and physical shocks can misalign or damage internal components. Keeping metal tools away helps prevent arcing or other damage in the high‑voltage area around the magnetron. While properly tuning the transmitter is important for correct operation, it does not address the magnetron’s physical integrity or its weakening, so it’s not a protective precaution for the tube.
