Discrete Tube amplifier 2SA1943 2SC5200
Discrete Tube Power Amplifier circuit using 2SA1943 2SC5200 , Output power this power amplifier circuit its according to the power supply voltage circuit, and amplifier power tube which will be different, such as the power tubes 2SC5200, 2SA1943 at + /-50V supply power up to 120 watts at 8 Ohm Impedance. But this power amplifier need supply voltage about +-30V up to +-50V Dual symmtriccal the need to replace withstand higher voltages higher capacitance. Reference 2SA1943 2SC5200 : 2SC5200 2SA1943 Transistor
This is a circuit of mono amplifier , to stereo circuit, need two series of mono, power amplifier has a very good sound performance, the differential input transistor 2SC2240 and 2SA970 Toshiba Original, push tube 2SC5171 and 2SA1940, Toshiba imported. Select T oshiba encourage imports of pipe 2SC5171 and 2SA1930.
2SC5171, 2SA1930 Toshiba bipolar transistor, the role of 2SC5171, 2SA1930 is to promote the management. 2SD669 imported Hitachi silicone tube NPN, 2SD669 operated in the status of the class single-ended, positive and negative signal half-wave by 2SD669 itself, so there is no crossover distortion, and even the wealth of harmonic timbre there are a few roles moist, and thus boards enlarged very resistant, but 2SD669 work in a large current status 50mA (normal op amp, integrated amplification only a few milliamps), to handle the large dynamic music signals easily get the most realistic sound performance! Playing a major effect! ,
