This is the PCB of a single channel power amplifier. The circuit is with reference to power amplifier section of Accuphase E-350 integrated amplifier. E-350 is one of the most successful and welcome integrated amplifier for its refined, detailed and musical performance. We modified the circuit a little bit to make it more suitable for diy purpose. The circuit has equipped with DC servo circuit to minimize DC drift. Circuit features : 1. Current feedback architecture - low distortion, broadband and high speed ; 2. DC-servo for minimal dc offset at the output ; 3. Compact size PCB ( not to mean the circuit to be simple !) PCB thickness 1.6mm. Dimension : 102mm x 83mm We do air shipping worldwide at US$4.00.
This is a single channel board. For stereo application two pieces are required.
