Product Details:

① Copy QUAD405-2, unlike QUAD405. Using the original imported TL071 JFET operational amplifier. Using the original imported ONSEMI power pipe

② It is the later improved model of QUAD company in 405.

③ The plastic transistor has better performance than the earlier metal power tube.

④ And more convenient installation.

⑤ All resistors are made of solid metal film resistor copper pin, 1% accuracy, including high power resistors.

⑥ The inductance is manually measured by a precision digital bridge, accurate to 0.01UH 0.1%.

⑦ Working voltage: + -30V to + -50V

⑧ 100W 8R power (+ -50V)

⑨ Power plug Description: VCC+ positive power. GND power ground wire. VEE- negative power supply.  INPUT input signal + -

⑩ Output: OUT+ output speaker positive, speaker negative directly connected to the power supply board GND ground wire.

Package Included:

1 × Stereo Finished Board (2 boards)
