  • Burns Sonic 30 guitar combo

    Hi - new to the forum. I run a service centre here on the Isle of Wight in the UK, and I have Burns Sonic 30 guitar combo in for repair. Does anyone have a schematic for this? Thanks in anticipation, Mark.

    The only item that I ever found is the Orbit3.

    It may give some clue as to what you have.

      Great, thank you very much! Looking at the PCB/components, it's may be much the same - the main difference is that this one does not feature reverberation. Incidentally, this amp works, but has a high degree of white noise. Looking at the circuit, if it's the same, this would appear to originate from the first two preamp transistors given that the treble control affects it - I wonder if this is normal, being such an early transistor amp.. If not, I'll be resorting the 'scope.....
