NAIM NAC42.5 NAC42_5 Classic Pre-amplifier Finished Board AC 20V-24V

Description: NAIM NAC42.5 NAC42_5 Classic Pre-amplifier Finished Board AC 20V-24V Description: The NAC 42.5 predecessor is widely praised in the UK and is considered by the British to be the most prestigious predecessor in the world. Although it is a bit exaggerated, but you can still imagine the high praise of NAC42.5. Using TOSHIBA audio ultra-low noise signal tube. Using imported tantalum capacitors. Input and output coupling capacitors. Power supply range: AC single 20V to AC single 24V. You can use dual 10V or dual 12V AC in series to get a single AC20V. Using precision voltage reference source ONSEMI Motorola LM317T plus OSCON polymer semiconductor capacitor As decoupling filter capacitor Then add LC large-capacity inductance and capacitance as a secondary filter. Effectively reduce power supply noise. The circuit adopts NAIM UK original circuit SN> 100 DB PCB area is 65 * 87 MM Voltage gain magnification = 11 times THD + N <0.05% Frequency response = 20HZ-20KHZ -0.2 DB Input impedance 330K Static working current 22MA The filter capacitor uses the original Panasonic FC black leather gold audio capacitor The signal coupling capacitor adopts straight tantalum capacitor imported from the United States.
