50MW Audio Amplifier circuit The following is a small audio amplifier comparable to what you may come across a small transistor radio medium size. The input stage is biased to ensure that the power is divided equally to provide the two complimentary output transistors which are slightly biased in conduction of the diodes between the bases. A 3.three ohm used in sequence for the use of the issuers of the output transistors to stabilize the bias current that does not change significantly with temperature or several transistors and diodes. Due to recent increases in bias voltage between the emitter and base decreases as a result of minimizing driving. Input impedance is 500 ohms and the voltage gain is approximately five to eight ohm speaker connected. The voltage swing around the speaker is 2 volts without distorting production and capacity is at the same time in the 50 milliwatt range.

Single Ended Valve Triode Amplifier has not same tone with Push Psu Amplifier. Over 90% of Amplifiers are push pull, and push pull amplifier does not 2nd harmonic and off course does not get 2nd 4th, 6th harmonic vs SE has 2nd, 4th, 6th harmonic. Push pull has minor distortion than SE Amplifier.2nd harmonic is make good tone for Music.not too much and not less than.feel good sound get from Single Ended Amplifiers with high efficiency speakers from 88dB/m to 100dB/m. I means Single Ended Amplifier is almost Single Ended Triode Amplifier.or Penthode but wired Triode. Tone is Different.good for Jazz and small room Classic.   KT88 Tube Power Amplifier Class A Circuit
