Pioneer A-676 specifications

External differences from the A-656 MKII: Golden dot now on the volume potentiometer, input and output selector switch. Inside: now vertically mounted boards, thus a clear view through the base plate, which no longer consists of copper, now also no honeycomb housing around the relay section and the RCA boards. (Savings against over the predecessor !)
