Does anyone have this schematic?

Is it much different from the V1141? The 1141 schematic is available on this forum in at least one thread. Try a search for that.

The third generation preamp used in the V1143 Beatle amp was designed for V1123 Buckingham, V1133 Royal Guardsman, V1154 Viscount and V1143 Beatle.
The third generation preamp used FET transistors in the preamp and in switching Distortion Booster and MRB.

The preamp and control section used in the V1133 Royal Guardsman was identical to that found in the V1123 Buckingham and V1154 Viscount.
The only difference between the preamp section of the V1133 Royal Guardsman and V1143 Beatle amp was the inclusion of the "Repeat Percussion" effect in the V1143 Beatle.
