It is the later improved model of QUAD company in 405.
It is also a lot of sales on the market. LJM is imitated. The plastic transistor has better performance than the earlier metal power tube.
And more convenient installation.
All resistors are made of solid metal film resistor copper pin, 1% accuracy, including high power resistors.
The inductance is manually measured by a precision digital bridge, accurate to 0.01UH 0.1%.
Working voltage:
+ -30V to + -50V
100W 8R power (+ -50V)
Power plug Description: VCC+ positive power. GND power ground wire. VEE- negative power supply.
INPUT input signal + -
Output: OUT+ output speaker positive, speaker negative directly connected to the power supply board GND ground wire.
The bottom of the AP SYS 2 TEST test data is:
Using the original imported TL071 JFET operational amplifier
Using the original imported STMicroelectronics power pipe 2SC5200
