* Currently sold is the Ishino Lab Master Series designed by Mr. Hirano, an engineer from the original Sansui. An X current circuit is adopted to achieve a maximum of 12W. This time, it's a custom model where you can listen to the STAX Year SP. There are no noticeable scratches on the exterior (Tamura Eiji)
Maintenance information: 2023.10.19 Operation confirmed (STAX output is unchecked)
Accessories: instruction manual, power cable
Main Specifications: 12W+12W (8Ω) W230 ✕ H95 ✕ D269mm Weight 3.6 kg
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)
Maintenance information: 2022.10.24 maintenance (transistors, electrolytic capacitors, SP terminals, rectifier diodes, fuse resistors, cement resistors, fuses, relays, LED lamps, heat dissipation sheets exchange.
