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.
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.
