B5 buffer stage before using low-voltage supply ( about +/- 25V), ensure safe use.
DALE 1% high-precision metal oxide film resistors , no sense , and low noise.
105 ° high-frequency low-impedance capacitors Japanese chemical , longevity, stability, and improve the high frequency performance.
High impedance input , avoid bad connection contacts cause signal loss.
Low impedance output , better after the driver stage , improve the high frequency performance and transient response .
Changeable with series for 6DJ8/6922/ECC88/6N11/6N23P; 12 series for ECC82/12AU7/12AT7/6N4 (with changing of jumper)
Connection : CD or other audio source -> B5 Buffer – > Amplifier
