Re: Pioneer VSX-520-K Protection problem



That's an interesting theory, but it would have to be a pretty bizarre set of circumstances for poor earthing on an input at the pre-amp end to cause DC on the output stage of the power amp!

That said, I just managed to cause DC on the INPUT of my VSX-520, taking out C206C with a loud bang! This is a good example why you should use the service manual, even when you're experienced and know what you're doing. I dived in without the manual, replaced the output transistors and also needed to replace the protection...
