4.8.2 +12V and -12V REGULATORS (SCHEMATIC #63002308)
The voltage generated by the 35 VAC center-tapped secondary winding
of Tl is used as inputs to the +12V and -12V regulators. The operation of both
circuits is identical to that of the +5V regulator described in Section 4.8.1.
4.8.3 +35V POWER SUPPLY, UNREGULATED
The 26.5 VAC output from the transformer is rectified by diode bridge
MOl and filtered by R19-C15 to generate the +35V unregulated voltage for the
power driver circuits. All of these components are located in the electronics
cavity. The +35V output is fused through F5 and used as a voltage input to the
power driver board via connector PI3-JI3.
