Re: AZ31 as rectifier for a stereo Mullard 3-3?
Chassis ground like 0v & screen from tfmr all to one point near C1 or 1st big filter cap,then a bus bar goes to that too. Next in this order onto the busbar, OP stage, phase splitter if any, then IP stage & IP from RCA in. the idea being to keep high current grounds away from sensitive IP stages.
