It's a 3203 Artist 30 head. 2 EL84 power tubes and a solid state preamp section. IIRC the cabinet is was paired with was a small 4x10 instead of the more traditional 4x12 cabinet. I think at the time in 1987/1988 it was under $400.
The hybrid Artist series heads have a good reputation these days. They were mostly overlooked until the JCM800s started becoming collectible and people started looking for less expensive alternatives.
