This is essentially the AB763 circuit used in the Fender Twin-Reverb blackface models from '63-'67 with some additions that don't effect the original tone of the amp such as 4 individual bias control adjustments, added half-power switch, and impedance selector.  The one pictured here was a special order with bluesbreaker grillcloth, black leather style covering, Marshall multi-tap output transformer and an added MID/FAT boost footswitch.  12" speakers are a mix of the Weber Silver Bell and the Weber Ferromax 12-F-150A.  Email or call for pricing and options.
