1 Pair HM4S-P933 HIFI 2SA1216 2SC2922 Power Amplifier DIY Kit/Finished Board 150W+150W

The whole series of pure power amplifiers have extremely low output impedance and extremely high damping coefficient. Even the 933 with an output power of only 120W/4 Ω also has low frequency control power. It can cope with some speakers that are difficult to control. When it is matched with the Dynaudio series speakers, it has a very outstanding performance, and has an invincible noble voice.

Commissioning instructions:
