Boss Katana 50 Mk2 - Guitar Amplifier (Spares or Repair)

The amplifier turns on and all the lights come up but there is no sound output from either speaker or headphone output. We have been advised that it needs a new motherboard. The actual unit is in very good condition, only a few marks around the body.
