[QUOTE="John Roberts, post: 83167, member: 126"] Re: AC line loss causes hum Anything is possible but live SR is notorious for lousy mains power, so major manufacturers typically accommodate realistic low-line voltages. 110v is not an acceptable low-line voltage, but some high end designers live in a bubble, so don't have the experience gained from dealing with world-wide mains voltage variation. It isn't just low voltage that bites you. The outback is notorious for capacitor blowing high-line voltages too. But these are just two sides of the same coin, inexperience wrt mains voltage design tolerance occurs along side inexperienced input stage design for pin 1 rejection. JR [/QUOTE]
