6Z4+6N3 Tube Preamlifier Borad C2200 Hifi Valve Amplifier Preamplifer For McIntosh Circuit Design .
This product refers to part of the circuit of mcIntosh. After modification, the amplification function is added, the circuit is optimized, and the selected components of heavy materials are used, and the excellent effect is better.
PARAMETER:
1:N3 version AC single power supply - one set of high voltage between 150V-250V, two sets of low voltage between 6V-6.3V, tube available (6N3 6H3N, GE5670, 2C51, 6CC42, etc.)
2.N2, N3 version rectifier tube can use 6z4, CV394, U2M70, 6202 and other models. The two versions are only common to rectifier tubes, and other types of tubes can only be used with corresponding versions. )
3: This product is a front stage without power amplifier function, and passive speakers and speakers cannot be directly pushed. It can only be used with power amplifiers or active speakers, nor can it be used in cars.
4: The pre-amplification is about 5 times .
5: Two 6Z4 bile rectifiers are used .
6: PCB board size: 165MM*103MM .
The highest tube size is 66MM, and the highest capacitance is 43MM .
Material characteristics:
1.WIMA Fever Low Loss Coupling Capacitor .
2.German Siemens (EPCOS) fever capacitor .
3.Japan Nichicon (nichicon) sapphire capacitors .
4.There are also Japan Chemical Black King Kong KXG high-frequency low-loss long-life capacitors .
Tradition. Taste the military-regulated pure vacuum tube preamplifer design with its mellow tone.
Audio output: connect to power amplifier or active speakers
Audio input: audio source (audio source can be accessed: CD, mobile phone, MP3, computer, TV, etc.)
Note: 1.The high voltage cannot be directly connected to the mains and requires transformer isolation .
2.High voltage/low voltage must be seen clearly before connecting, the components will be burnt if plugged in the wrong way.
Package: 1pc.
