morning everyone.
I am planning to use the Gyraf g9 PSU to power my first attempt at a 1B NYD pre. Question: why did Dave design the PSU to produce a B+ of 300v but then the first thing the B+ hits in the one bottle is R13 which is a 1watt 10k resistor and c6 to drop the voltage to around 235V.
I am assuming if I build the G9 PSU stock (B+ 245V) I can simply omit R13 on the 1B yes?? Or is it best to reduce the values used on the G9 PSU to try to up the voltage to 300V??
