I recently bought a used B&K VMR-6.5.4 six channel amp to serve as a dedicated lspCAD pro crossover simulator amplifier. It all seems to be OK with it. I looked inside and there are no op amps in the cuircuits, just transistors. All in all pretty minimalistic design. Power supply caps are huge (4 x 20000uF). My question is: where can I find some more info about this amp? I emailed B&K but haven't heard back for at least a week. Google search comes up with nothing interesting. In particular I would like to find a service manual and technical specs. Anybody?
