Burn in transmission valves
Valves that is missing a getter contains air that needs to be removed before the valve is taken into service. Connect the filament. Check that no flashes occur.Connect a resistor of 1Mohm 0,25W in series with the anode power. This reduces the anode current so the valve gets a soft start. If you burn the resistor, just replace it. When the process is finished, no flashes occur in the valve.
Cheramic valves is burned in by just connect the filament and have it on for 12 hours.
