KHD-1000 Headphone/ Desktop Amplifier Direct Coupling AMP Kit EH-6922 Tube Amplifier Kit

 

 

 

Note: this is a DIY kit, all the components need yourself to solder and adjust.

Note: The kit with K1058-J162 two pairs, EH-6922 tube 2PCS.

 

 

KHD-1000 system with reference to a gallstone foreign direct coupling circuit which has the following characteristics:

 

1, Using a tube differential differential differential circuit, four circuit architecture, MOS tube power output;

(TUB + BJT + BJT + MOS)

2, All the discrete structure, high-current MOSFET tube output stage, at all levels in the CPI state, the whole circuit is a pure Class A! With low distortion, low output impedance, high output power!

3, Do a differential input stage tubes, tube JFET tube can be similar to the high-performance, small nodules super capacitors, coupled tube will be a unique musical taste at low pressure (60V) lower;

4, Complementary push-pull output stage following the design, use of high current MOS tube! You can get a good driving force;

5, MOS tube is no "second breakdown", and the Department of negative temperature coefficient, the circuit does not require any thermal compensation, to reduce complexity, eliminate the effects of amplitude compression circuit, to provide maximum sound transparency

6, MOSFET tube multi-board electronic devices, the speed is faster than similar BJT, shed extremely impedance is very high, can simplify the drive circuitry required to provide high current high speed action!

7, Class A working condition. No crossover distortion, reduce the harmonic and intermodulation distortion

8, High output power, can provide more than 50VP-P voltage, easy to drive any headphones

9, Pure two-channel AMP modular design, reducing post-investment costs

10, One machine (amp / Desktop amplifiers), servo plus or minus 30V supply, there is enough to push a slew 4-600 ohm load; with the restaurant headphone - amplifier protection circuits can be switched to the amp / Desktop Amplifier , one input may be equal to two system.
