I'm on the lookout for a clean, fully functional 1976-80 JMP 2203 (serial H, J, K, L M), a 1981-84 vertical input JCM800 2203 (serial N, P, R S) or 1987-1991 JCM800 2210 (serial V, W, X, Y Z).
I'd be interested in selling or trading my very clean 1990 Mark III+ green stripe long head that's been modded & serviced by Mike B. Having had 9 of them I will say with confidence this amp is as good as IIIs get. I'd put the value on this amp with the III+ mod & factory service history at $2950 shipped.
