*: Focus quality: with Va3=800 and Va2 and Vg adjusted to give
an optimum-focus raster of convenient size and of light output 0.002
candles, the +ve grid drive from Vg (blackout) is noted (= x). Then,
with the beam just "blacked-out", a nominally square wave +ve pulse of
peak value x volts and of width 100µs at 100cps applied between
cathode and grid, and with the high frequency timebase set to produce a
line of 2.5cm in the x and y axes successively (with no adjustment of
focus between measurements in the two axes), the line width as measured
at the centre of the trace must not exceed 1.0mm.
