    Sony TA-N77ES Power Amplifier - Help with VU Meter

    Sony TA-N77ES gets hot and right channel fades out?

    Sony TA-N77ES

    I found a Sony TA-N77ES on the street today. It looked somebody just emptied out a bunch of stuff from someones apartment and this was on the street. It almost killed me carrying it home, it is really heavy. It seems way more complicated than the Technics SA-505 that I use now, what do you...
