When it switches off the speaker, try to measure the voltage at the common ouput point from each final stage. The voltage there should be around zero volts. If not, the fault should be found in that final stage. Look for "dry" solderingjoints. Cool down the transistors (pre-drivers drivers, final ones) with "cold-spay", and observe the voltage. If there is a termal problem with one of them, you see it rightaway. Unfortunately I have no diagram otherwise I could give you some more hints about it. Important: NEVER force the protectionrelay on with speakers connected. This will deteriorate one of them, including the faultly finalstage ! Good luck and kind regards.[/quote]
