While testing its functionality, suddenly the speaker was muted. Neither the ear-phone socket works. Maybe it’s a relay problem? My main concern is how to access to the amplifier section. I have the service manual, but found no hint. Thanks in advance. Author Posts Viewing 1 post (of 1 total) You must be logged in to reply to this topic.
