Re: Marshall Stanmore Repair

Hi,

In my speaker main amplifier is totally fried also some pcb tracks are missing. I traced that everything else is working even PWM signal processor/driver TAS5508C (below the shield) is outputting correct pwm signals to powerstage.

Has anyone measured powerstage input voltage? Mine shows about 31 volts. Other voltages seems to be ok, but is that 31 volt correct?

Do anyone any clues what else might be broken when amplifier chip is broken? Has anyone one anyled why that powerstage fries itself?
