Rated Excellent on Trustpilot.
This very good NAD 2400 stereo power amplifier, manufactured in 1979, has been fully serviced and is tested and working.
Description from the seller
Fully Serviced legendary Stereo power Amplfiier from NAD.
Unit has been recently fully serviced and what has been done to the unit is the Following:
-Completely recaped the whole Amplifier PCB.
-Replaced all Signal Transistors.
-Replaced all Driver Transistors.
-Replaced all Power Transistors.
- Replaced all Diodes.
-Replaced alot of Resistors.
-Recalibrated the bias.
-Completely washed the whole device.
The NAD 2400 is a legendary stereo power amplifier from the well-known Monitor Series, produced between 1989 and 1992. The amplifier is known for its enormous dynamic power and stability, thanks in part to NAD's patented Power Envelope technology and a dual-rail Class G circuit. Many copies also carry a THX certification for home theater applications.
Key specifications
Continuous power (Stereo): 2 x 100 watts RMS at 8 ohms
Continuous power (Bridged mono): 1 x 300 watts RMS at 8 ohms
Dynamic peak power: 370W (8 ohms), 400W (4 ohms) up to 440W (2 ohms) in stereo. Bridged, it reaches peaks above 800W.
Peak current: Up to ±40 amps, keeping it very stable with demanding low-impedance speakers.
Total harmonic distortion (THD): < 0.03%
Weight: 10 kg
Special features
Soft Clipping: Switchable NAD protection that rounds off hard deformation (clipping) when the amplifier is pushed over its limit, protecting your speakers.
Impedance switch: On the back there is a switch to optimally adjust the transformer taps to 4 or 8 ohm speakers.
Input Levels: Features adjustable input sensitivity (useful if you want to connect a source with volume control directly) in addition to the standard THX inputs..
