Hello all: This is my first post in this fine forum. I have a Sony home entertainment system I purchased back in the middle 1990´s. It´s been a good system but the power amp finally quit. All the other components work fine, but you gotta have to power to use them. Anyway, if anyone has a good working Sony TA-AV411 amplifier or compatible that they´re no longer using or need, please let me know. I´d be interested in obtaining from you, since I hate to discard my sound system just cause I cannot replace the power amp. I contacted Sony and they said they have nothing in their current stock to replace or substitute my power amp. Anyway, thanks to all who read this and hopefully someone can help me out. Thanks.
