hi guys , i have a problem and i started a Thread over at a Electronics forum and haven't got a reply so i am re-posting it here to see what's happened.
update........... fixed the Amp today which i'm stoked about. I reflowed all joints on the main PCB and now it's up and running again , i would like to mention that if you are going to clean a PCB and the solder is quite old you may loosen one of the joints like i did. So yeah if you clean a old PCB you may need to reflow the joints after it.
