Pay attention to powering up the amp with the batteries for the first time. I suggest purchase of the 19 v AC adapter to “initialize” the amp and battery card. Parts Express will answer any technical questions you about this procedure.

Very pleased with the outcome. Very smooth sound across the frequency range. All parts were purchased from Parts Express, with th exception of wood for the cabinet.
