[QUOTE="fredeb, post: 898207, member: 13623"] Fabrizio - if you look closely at the power supply schematic you will see that a voltage doubler is being used , so rectified B+ is theoretically ~380V without voltage drop caused by load . After the voltage drop the anode voltage of the 807 is probably approximately 300V . Remember that the drop is caused by components across the whole circuit x2 ( L & R channel ) . [/QUOTE]
