The trigger is a [[6DJ8]] trigger amplifier followed by a 6DJ8 Schmitt trigger. | The vertical amplifier consists of a [[12BY7]] differential amplifier followed | ||
by a [[6DJ8]] cathode-follower, followed by a [[6197]] differential (common-cathode) | |||
output stage that drives the 200ns L-C delay line, which drives the vertical deflection | |||
plates of the CRT. | |||
Trigger pickoff is taken after the cathode follower stage in the vertical amplifier. | |||
There is a 6DJ8 differential trigger pickoff amplifier followed by half of a 6DJ8 a | |||
cathode follower, buffering the trigger signal. | |||
The trigger circuit is a [[6DJ8]] trigger amplifier followed by a 6DJ8 Schmitt trigger. | |||
Triggering can be from the internal pickoff or from and external signal or "line" trigger, | |||
from a 6.3V tap on the power transformer. | |||
The 533 contains a 128F [[thermal cutoff]]. | |||
The high voltage for the CRT, +8650 and -1350, are generated by a 60 kHz Hartley power oscillator and | |||
five [[5642]] high-voltage rectifier diode tubes. | |||
