North Coast Music - UK Schematics - AC-30 1959 to Present

North Coast Music offers nineteen different schematics for the AC-30. As there have been at least this many variants of the AC-30 in the last thirty years, you will have to first ascertain which schematic you might need. I have tried to be a thorough as humanly possible in describing each AC-30 model and hope you can choose the appropriate schematic you need.

Please do not ask me to choose the right schematic for your amp, you will need to do this yourself from the information I have provided here. Additionally, serial numbers are not helpful in determining which schematic you need. Please do not send me your serial number or photos of your amp, I cannot pick the right one for you.
