This is the bare PCB of an ultra high-end power amplifier. The power amplifier is with reference to Burmester 933 mkii which is one of the best power amplifiers in solid state league. In the original design, two channels were put onto one board with the power transformer sit in between two audio channels for an integrated structure. In our incarnation, each board presents one audio power amplifier only. This allow users to build either a monoblock amplifier, or a stereo amplifier by putting the boards on the two sides of a housing for best heat dissipation. On the other hand, we strictly follow the original designs layout rules for integrated rectification, power filtering and dedicated low impedance low noise regulator for the input and VAS stage. Supply voltage : AC 36Vx2 to 44Vx2 400VA per channel This is a PCB for a single channel of power amplifier. For stereo application two pieces are required. We provide schematic and part list by email ( attached to the shipment notice on the item posting day). PCB dimension : 285mm x 102mm. We do air shipping worldwide at US$7.00.
