Including: Two pairs of German original imported field effect tubes, including a pair of Japanese chemical 50V6800 UF original capacitors.

L12 amplifier board using field-effect tube output, each channel using a pair of IRFP140, IRFP9140 high-power, high-current field-effect pair of tubes.

IRFP140 parameters: 100V , 33A, 140W.

IRFP9140 parameters: 100V, 21A, 180W.

With its own rectifier filter circuit, AC power supply .

L12 is designed with no coupling capacitor input, input signal voltage avoid DC.

Adopt 25A rectifier full bridge, 50V 6800UF two original filter capacitors imported from Japan.

 

L12 parameters:
