1pair LJM L12-2 Dual Power Amplifier Board Low Distortion Class AB AMP
Parameters
Power = 120W /8R + -50V voltage
200W 4R + -50V voltage
THD<0.0005% 1K HZ 10W
SR = 35V/US
Damping factor >200, 8ohm load
Input sensitivity=1.6V output 120W 8R
Frequency response range = 15HZ-50K HZ (-3DB)
20HZ* 20K HZ =-0.02 DB
Quiescent current = 80MA
Voltage use range = DC positive and negative dual voltage + -12V to + -55V
Voltage magnification = 31 times
Features:
PCB with 2MM thickened material 75 UM thickened copper film
The quiescent current of each channel is 40MA and works in CLASS AB.
The small signal tube uses the original TOSHIBA low noise tube, and the original ON low noise tube is used as the current source and voltage amplification.
The output tube adopts the original imported Sanken ultra-high frequency FT 70M, multi-emitter LAPT audio famous tube.
2SA1186 2SC2837, two pairs of output tubes per channel.
Humanized installation method, one channel only needs to install the big pipe on the radiator.
And the big tube can be arbitrarily installed on different radiators
Under + -50V. 8 ohm load can output 120W power
