NAIM NAP250 MOD
（this price is for 2 channel board/kits)
The DIY kit version will need yourself to solder all parts. Assembeld board we will solder and test it well before shipping.
It is an imitation of nap250 by LJM and an improved version.
Compared with Naim nap140 200, the performance is better and the price is lower.
Nap250 mod version adopts mini circuit board design scheme to reduce the length of PCB wiring.
It also reduces the resistance influence of PCB wiring.
The shorter the PCB copper wire, the smaller the resistance and the performance will be improved.
In addition, some bugs of the original factory have been modified in the nap250 mod version. The temperature compensation tube can be installed on the same radiator as the high-power tube.
In this way, nap250 mod can work in classAB
crossover distortion is avoided
And several other obvious bugs of the original factory.
Therefore, the effect of nap250 mod is better and more cost-effective than the original copy.
The weight of two dual channel boards is 100g, excluding the weight of the package.
Operating parameters:
The supply voltage is DC + - 15V to DC + - 40V.
Output power = RMS 80W 8R (DC + - 40V)
Recommended value of static current: voltage at both ends of cement resistance = 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）
