Sony TA-N80ES

[anonbeat]

Hello,
Im a happy owner of a Sony TA-N80ES power amplifier. Recentry it started to go to protection just few minutes its powered on. I thought at first it was a bad speaker connection but it wasnt. Im trying to get the service manual or squematics to repair it. Do you think it worth to repair it or should i go and buy something else more actual?

thanks in advance

Only have manual for TAF-F333ESR and 703ES which should be very similar if not even equal.

You´ll get them if you name your email adress.

Hi anonbeat,try to check the DC offset voltage.

I guess i finally fixed it. I adjusted both... the DC offset trimers and the v bias trimmers. It was tricky to get the proper values as minor movement did difference but i did my best. Now its been testing it for more than a half without protection.

Thank all for replies and SOP for sending the service manual
