Notice:This is just diy kits for professionals.You have to assemble it by yourself.Thank you!~
Parameters
PCB size: 67.5x48mm
Power supply voltage DC + - 15V to DC + - 40V.
Output power = RMS 80W 8R (DC + - 40V)
Quiescent Current Recommended: Voltage at both ends of the cement resistor = 1.5 MV-3MV
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.
NAIM NAP250 MOD is base on the famous NAIM NAP250, Better performance than NAIM NAP140 /200， and the price is cheaper.
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
