I am completing parts order for AU-9500 restoration, one last thing I am not sure about are filter caps and rectifiers. Original caps are puny 4700mF and should be brought up to at least 6800mF but what worries me are the rectifiers. They are already well known to be unreliable and upping the capacitance would put even more stress on them. Which rectifiers would be a good solution, either as plane replacement with original 4700mF values or even better for 6800mf - 10.000mF ? And what about the power switch, would stock one be O.K. in 9500 "turbo" version?
