Assembled LJM L12 Stero power amp board FET output with rectifier filter CL-188
L12 using FET output amplifier board, each channel using a pair of IRFP140, IRFP9140 high-power, high-current field-effect on the tube.IRFP140 parameters: 100V, 33A, 140W.
IRFP9140 parameters: 100V, 21A, 180W.
Comes with rectifier filter circuit, use AC power supply directly.
L12-free input coupling capacitor design, the input signal voltage to avoid DC.
Using full-bridge rectifier 25A, 50V6800UF Japan imported original filter capacitor.
