just an idea

Slight update is that I've been able to change my transformer for one with a center tapped 190v-0v-190v secondary. So I think this will give me (190 x 1.414) 269v into the EZ80 rectifier. I'm struggling to figure out what the voltage drop will be, but will soon find out once I've started building it. Assuming my output voltage needs adjusting, would it be best to do this by changing R15?
My other question for now is about grounding. Would it be best to
1. ground everything direct to a bolt though the chassis as a star ground?
2. keep my ground separate to the chassis ground. And have chassis connected to mains earth?
3. Same as above but connect chassis ground to to my separate circuit ground via a resistor?
I've got 3 different books I'm reading alongside this project which suggest each of these, just trying to pick which will be best.
