Output up to 500 Watt Mono, 1000 Watts for the stereo amplifier circuit. Amplifiers: Output stage Lenard Audio The first large silicon transistors (2N3055) enabled power amplifiers to be capable of 50 Watts but were only available as NPN and not as PNP. When PNP power transistors (2N2955) became available they were twice the price. The output transistors on the V rail appear not to be wired as emitter followers. Audio Amplifiers techlib The speaker should be rated at 500 mW or more and should exhibit a DC resistance near 8 ohms (perhaps 7 ohms). Check the candidate speaker with an ohmmeter; much below 7 ohms will cause excessive current draw. With the 220k resistor and 16 ohm speaker, the circuit draws about 100 mA (500 mW) and delivers about 125 mW to the speaker. Best sounding transistors | Audiogon Discussion Forum For example, when you compare an amp with 4 output transistors (2 for positive waveform and 2 for negative waveform) with an amplifier that has 12 output transistors, the transistors on the 12 amp will work 1 3 as hard for the amp to push the same amount of current to the speaker. 1000 Watt Audio Amplifier with Transistors 2SC5200 and 2SA1943 This is the circuit design of 1000W stereo audio amplifier.

For improved speaker output a single transistor audio amp will be a great improvement. So what are our options? The Sound of Transistors | Stereophile A typical transistor amplifier will make any loudspeaker sound crisper, as though its transient response has been improved, but it is not the same kind of "crispness" we can get from a tube amplifier by just cranking up the treble. In a tube amplifier, treble boost will increase the "harshness" of disc distortion. Can anyone help me to make an audio amplifier using BC107 ... I can. Where are you?
