Re: [Amps] Gates RF103 3-1000

Is the 3-1000Z not like the 3-500Z in that the only way to get the 
gettering to work is through having the anode nice and hot? That is 
glowing nicely.
Therefore, it doesn't matter how long you let the tube run with filament 
and fan, no gettering is happening. That is my understanding.
