6.15. HVPS (High Voltage Power Supply) Section
6.15.1. HVPS Specification
As for the developing voltage, the DC voltage and AC voltage are overlapped and output from an output terminal.
There is one terminal for transcription output and + and - are switched to be output.
6.15.2. CHG-BIAS (Charge BIAS)/GRID/ UNIT
When IC300 turns on the transistor Q506, CHG REM becomes “L”, and Charge BIAS (200µA) is output from CHG OUTPUT.
GRID BIAS is generated by the current flowing in the GRID circuit via charge wire and GRID.
