Short description[edit]
External differences from the A-757: smaller knobs replaced by cylindrical versions resembling the large knobs. Golden dot only on the volume pot. Inside: still horizontal circuit boards, but already no honeycomb housing around the volume pot at the back right of the unit. No copper bottom anymore!
