Good luck! VTL does not give out schematics, even to authorized dealers, even on old models. When I needed to have work done on my VTL Deluxe 500 monos, my tech had to draw his own. Fortunately, he's good enough that he could.
VTL MB450 Schematic
I have a pair of VTL MB450 signature monoblocks. Has anybody got a copy of the circuit schematic ? I have been trying to contact VTL but getting no response. From reading some of the threads this is not unusual ! One of the amps is in for repair and the schematic would assist the engineer.
