Thanks, Jim I built this with the recent updates that you posted. for this power supply what is the voltage that the transformer must have?

Hello Jim, I'm building your own version of SRX amplifier and your shunt regulator PSU. Before ordering the transformer I would be sure of the necessary AC voltage. On the shunt pcb there is AC700 CT If VDC = VAC x 1.41 350-0-350VAC = 490-0-490VDC and if the shunt drop 20VDC I think the voltage is too high. Then the transformer should be 260-0-260VAC, correct? (200mA be enough?) Another question: how do I adjust the CCS shunt 10M90S-DN2540? What should I read on the 10ohm test resistor? 0.4V? 0.5V? Thank you
