/ At a peak anode/plate current of 1.2a, the 3-500Z is fairly linear.
At 1.4a peak, the curve is beginning to substantially deviate from the
desired flat line. / notes -- 1.2a peak corresponds to an average
current of c. 0.400A. 1.4a peak corresponds to an average current of c.
0.466A. I am sending you a separate e.mail of the constant current
curves in gif format.
