2SA1216 2SC2922 150W HIFI Power Amplifier Board Voice of Berlin 933 Circuit YJ00179 Electric DIY Amplifier

Features: Adopt disassemble tube 2SA1216 2SC2922 new opamp OP07 The front adopts direct-couple test amplification, and the whole circuit have no coupling capacitors, which reduces the distortions to 0.01percent. The resistors use highprecision resistors, and main circuit use highprecision resistors with accuracy of ± 1percent to ensure a goodsignal-to-noise ratios. The PCBadopts 1.6mm thick double-side sheet, and the whole process of tinspraying ensures the good passing performances of large and small current. Good PCBquality, good production process. This board can be debugged as ClassA ,ClassesB.
