(7) Remove bottom cover from TI (model 746A only). Remove plastic cover from
A6 amplifier assembly (fig. 7).
(8) Connect ac/dc voltmeter high voltage leads between test point B (fig. 7) and
GND (circuit ground).
(9) Press OUTPUT ON pushbutton.
NOTE
The voltages in (10) and (12) below do not have to be exact.
They may vary as much as 50 V. The important point is that
voltage difference between them is 30 2 V.
(10) Adjust A6R14 (fig. 7) to obtain indication of 1850 V dc on ac/dc voltmeter (R).
(11) Move ac/dc voltmeter leads to test point A6TP6 (fig. 7) and GND (circuit
ground).
(12) Adjust A6R77 (fig. 7) to obtain indication of 1820 V dc on ac/dc voltmeter (R).
(13) Press OUTPUT OFF pushbutton.
