ment voltage, which is fed into pin 1 of the 2F5 connector, and pin 8s ABL signal. For the filaments part,
since this voltage is needed only to heat the cathodes, it is not necessary that it be a DC voltage. ABL is fed
to the video processor in order to regulate beam current.

Pin 6 provides power for the +35V supply previously mentioned. RX3216 drops some of this voltage to
+33VSW, which supplies the tuners. Pins 9 and 4 develop, correspondingly, a positive and negative
14VDC. This ±14 volts powers the audio section. RX2125 and RX2124 serve as fusible resistors for the
±14VSW supply to the vertical amplifier, IC2100.
