1pair DIY NAP250 MOD Stereo Dual Power Amplifier Board Class AB AMP 80W ST 2SC5200
Parameters
PCB size: 71x48mm
High power tube: ST 2SC5200
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.
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
