1. Very low output impedance and high damping factor, with perfect low frequency control even though the output power is only 120W.

2. The output transistor is the original SANKEN transistor 2SA1295 and 2SC3264, and the main filter capacitor is up to 80000UF, ensuring powerful dynamics and abundant energy.

3. Potentiometer is Japanese precision ALPS27, no breakpoint all-copper a-core transformer, omron relay protection.

4. The input end is CMC of the United States, and the output end is pure copper terminal.



Packing list: power amplifier*1. (No power cord and other signal cables)
