PA-650 2U Amplifier
Using a fully symmetrical co firing differential circuit as the front stage, coupled with a co firing common base as a voltage amplifier field-effect transistor for high voltage switching excitation (gold sealed tube has fast heat dissipation speed, is less affected by temperature, stable sound quality, etc.), and equipped with high-quality aluminum as a heat sink, the heat dissipation speed is faster and the performance is more stable. By adopting comprehensive circuit protection, you can use it without any worries. The whole machine has rich treble levels, transparent sound, wide and smooth bass, and bright midrange.
