I am trying to get a schematic of the Cube 60 cosm so I can check voltages etc and try and find out why the amp sound suddenly packed up. All the inputs/buttons and knobs/tuner/line out work fine though the headphone jack. Extention speaker doesn’t work. Fully tested the speaker it’s fine.
Any ideas why the sound suddenly died and the reason gratefully appreciated.I have found schematics supposed to be the cube 60 cosm but none of them have been correct.
