Don't understand, buying Rolls Royce amp, but unwilling to send it to qualified engineers, to be fixed properly.

The driver circuit as i can make out is nearly the same as the Q & D series PSU driver apart from a higher frequency oscillator at the front end & some major re-work on the FET Bootstrap driver circuit and of course now all surface mounted components.

My problem is in this area mostly and because this part has changed a lot and some surface mount caps & resistors are burnt are unreadable, hence the circuit for this would cure the problem. The only other option is to copy the circuit from another board from a working amplifier & draw the circuit on my PCB CAD program (which is the easy part), but i don't know how long another Powersoft K10 will arrive at my repair bench with a working board in Cry.

Here's hoping for someone out there who has the circuit. Thumbs Up

send me your email at mgee626@gmail.com. ill send you clear picture of the board

The problem is, the K10 version has different capacitor values to the QD series. The only way to get the capacitor values is to lift the components out and measure them.
