200W MAJOR BIAS PROCEDURE

[DEXMAN]

DOES ANYONE KNOW THE CORRECT BIASING PROCEDURE FOR A 1969 MARSHALL MAJOR ? I HAVE SEEN VARIOUS VOLTAGES QUOATED ON THE WEB. I'VE ALSO SEEN THE SCHEMATICS THAT SURF POSTED A WHILE AGO BUT I HAVE POOR EYE SIGHT AND CAN NOT READ THE VOLTAGES THAT ARE PRESENT ON ONE OF THE DIAGRAMMS. TIA.
