2m246 Magnetron Datasheet ((top)) File

| Symptom | Likely Cause | | :--- | :--- | | Low output power, normal heater | Weak cathode (end of life) | | Arcing inside the vacuum envelope | Gas contamination (purple glow) | | No oscillation, normal Ib | Broken output window or loose magnet | | Heater OK, but no current at 5 kV | Internal open circuit in cathode coating |

The "2M246" designation follows an older industrial coding system. It is electrically and mechanically similar to the more common and MG5246 , but with distinct anode voltage and current ratings. 2m246 Magnetron Datasheet
