Marshall Mini Stack Schematics
The Mini Stack concept was introduced in 1984. The Mini Stack cabinets were smaller 4×10″ or 2×12″ versions of the normal 4×12″ cabinets. The heads were downsized accordingly to fit.
2204S, 50W head
The 2204S was introduced in 1986 and discontinued in 1987. It was the same amp as the JCM800 2204 but fitted in a smaller cabinet to match the mini stack size.

3203 Artist, 30W head
The 3203 Artist was introduced in 1984 and discontinued in 1991. The 4203 is the combo version of the 3203 head. Don’t confuse this amp with the older Artiste amps from the 1970s. The preamp is solid state, only the power amp uses tubes.
