Amplifier circuit diagram (with negative feedback)

Published:2011/4/8 0:59:00 Author:Ecco | Keyword: Amplifier circuit , negative feedback

Figure 21-5 is an example of amplifier circuit using A,Ba. The maximum input voltage amplitude is 52V between two grids of 6L6. The output voltage of each 6F6 anode should be half of 52V, that is 28V, then the output voltage in cathode is easy to get. As 6F6 is cathode output circuit, the gain of a2 ' is less than 1. But if a2 ' is equal to 1, then the maximum output voltage 6AU6 is also equal to 26V. Now setting the gain a1 of V1 is equal to 145, you can find the net between the gate and the cathode input voltage.   (View)

The push-pull amplifier circuit diagram 2

Published:2011/4/8 1:21:00 Author:Ecco | Keyword: push-pull amplifier

Figure 21-2 is a common push-pull amplifier circuit; And the tube can work in the class of A1 or AB1. As invert tube V2 has no amplification effect, it can be seen as polar amplification. Feedback resistor R1 is separate from the cathode bias resistor, the feedback resistance is only 10Ω, the resistance is very low, so the feedback current of V1 tube is negligible. Inverter circuit adopts the way of Figure 20-6, it does not use the transistor but use pentode, for simplicity, the balance of output voltage of the inverting tube is seen as 1.   (View)
