The method o f system reset, po wer up/down via mains swit ch and standby mode has
changed from that of the CD73.
When the CPU is reset by the LM809, IC300 on the display board, after a short
delay, approx. 200mS, the ~STANDBY line goes HIGH.
The ~STANDBY line, in turn, generates 2 more timed signals.
1. ~XRS T, the system reset line, w hich goes HIGH 1s after the standby line goes
high, and is also gated into the 10DAC power-on mute cct.
2. ~PWRDN, which switches off all the unregulated supplies except that which drives
the +5VD to the CPU.
This delays the LV power being switched off by 1s after the output is muted.
The XRST line from the CPU is no longer used

The drive voltage to the NPN & PNP digital
transistors is separated in order to prevent an
indeterminate bias voltage appearing on their
