The deteriorated capacitors and transistors were thoroughly replaced and refreshed. Plus, a full overhaul of speaker terminals and RCA terminal replacements! The BA-2000 was created to reproduce the sound of music itself. The low-frequency sounds are amazing power amplifiers! I get the feeling that the piano is bouncing and the saxophone is approaching from below. Please experience this feeling (Murakoshi Yoichi)
