Sunfire 300 Two Amplifier Schematics or Service Manual

hiran · 21st March 2011, 10:04 AM

Hi,
My Sunfire 300 x 2 stopped working, The volume is down and sound output seem to be in high frequency area, both channels are the same, removed the RCA cables from the pre amp and touched the tip of the connector to induce 50hz hum but the output of the speakers gives a very high pitched sound, since both channels are the same I belive the problem is in the Tracking Down converter. checked the board but couldnt find any blown caps, resistors or Fets. any advice is appreciated

Kind of old to reply to, but for the sake of future readers, Sunfire keeps a death grip on service manuals/schematics. I've never seen one show up ANYWHERE.
