The +50V section is produces the reference voltage for the other sections. | The +50V section is produces the reference voltage for the other sections. | ||
It uses a 9V zener diode, VR1412, as a reference. | It uses a 9V zener diode, VR1412, as a reference. | ||
The dependency relationship of the supplies is: | |||
* The -50V, -15V, +5V, and +15V sections depend on | |||
** the +50V supply for reference voltage, | |||
** the opamp supplies for to power their opamps, and | |||
** the A24 semi-regulated rectifier outputs | |||
* The +50V depends on | |||
** the opamp supplies (+22V and -5.6V) for to power its opamp, | |||
** the A24 semi-regulated rectifier outputs (-54V and +54V) | |||
* The opamps supplies depend on | |||
** the A24 semi-regulated rectifier outputs | |||
* The semi-regulated rectifier outputs depend only on mains power to enter tick/burst mode. However, to enter normal mode, a variety of things need to be working properly. | |||
