Marshall Artist Schematics
The Artist amps had a tube power amp and a solid state preamp. Don’t confuse these amps with the 1970s Artiste amps. It isn’t quite clear to me whether or not these amps were actually part of the JCM800 range, as these amps don’t have the JCM800 logos, but they were included in the JCM800 catalog and they were manufactured in the same period and had the same looks and style.
