I am planning to build a little single-ended EL34 guitar amp with some existing junk box parts. My power supply will provide about 345VDC and the output transformer provides a 3800 ohm load at its input. Does this EL34 operating point make sense? [see attached pic.]

I lowered the G2 voltage to 250 to get Vg1=0V in the right neighbourhood. I thought I'd ask here before I wired up something less than optimal. It seems fine to my inexperienced eyes.
