Output power = RMS 80W +80W 8R
Quiescent Current : Voltage at both ends of the cement resistor = 2.5MV
The current is about 10-20 MA.
THD + N = 0.001% -0.03% (20HZ-20KHZ 5W-30W 8OHM Audio Precision 2 TEST)
Frequency response: 20HZ -0.04DB, 20KHZ -0.34 DB
15HZ -0.05DB, 30K HZ -52DB.
NAP250 MOD is base on the famous NAIM NAP250, Better performance than NAIM NAP140 /200. the amp and PSU are using Split design.Reduce interference as much as possible.
NAP250 MOD using MINI circuit board design, reducing the length of PCB wiring.
While also reducing the impact of PCB wiring resistance.
PCB copper wire shorter, the smaller the resistance, the performance will be improved.
In addition NAP250 MOD version of the original modified some BUG. So that the temperature compensation tube can be installed with the high-power tube in the same radiator.
So that the NAP250 MOD can work in CLASS AB. To avoid the cross-distortion.
Main materials:
1: 200W Oxygen free copper Toroid transformer to ensure adequate power
2: original power transistor D1047 + original ALPS volume potentiometer.
3: aluminum chassis + stainless steel switch, feel first class
4: The machine has a perfect speaker protection circuit
5: high-quality copper output terminals
Package include: Finished NAP250 MOD Stereo power amp X 1
Finished Power supply X 1
0.6M DC cable X 1
Default is not include the AC input cable and other Audio cable.
(When you choose "No volume control" . the power amp will no voume konb. just a blank front panle)
