Cambridge Audio A4 Burned resistors
I wonder if anyone can help me...
I have a cambridge audio A4 amp which has 27volts on the speaker terminals. I have checked all output transistors and they are fine, but there are two burned out resistors on each channel.
Does anyone have a circuit diagram, or know the value of R214, R216 and R256 and R260? These are standard 1/4 watt resistors but the value is burned off and two of the transistors now read so high that it would be impossible for 47V to burn them, so they obviously were lower in value.
If you don't have a circuit diagram or manual, but own an A4 a good quality photography of the board should enable me to get the values...
Can you help?
Thanks - Chris
