Hi, as the title suggests I need the wiring diagram for the Advance Acustic MAX-450 amplifier. I can only find the quick user guide online. The amplifier has a channel which after a few minutes of operation destroys the power transistors by sending 45 volts to the speaker output which destroys the speaker itself. I have already replaced the final and pilot transistors twice and checked all the capacitors and resistors in that section but without a diagram I can't solve it. I hope someone can help me. Thank you.
