6 12 Volt audio amplifier circuits
The above is an amplifier circuit using supply voltages from 6 volts DC to 12 Volt DC. Power output of the amplifier is quite low with only 1 Watt 8 ohm impedance. You can apply this to the audio signal amplifiers that require strengthening are not so large as in the pocket radio.

6N2P Tube Pre Tone Low Volt Low Cost Circuit
That if one wants to create a high fire. Put values as I get it offline … because I reference values from the Data Sheet.
But do not suggest we fire up to 250 Volts Capacitor find the 350v. The price is expensive and over again.
I recommend creating a 230v. And then use the Cap 250 v. easy to find cheap used instead of the sound was no difference between voltage 250 to 230.

9 20 Volt amplifier circuit
For this time I will post the scheme following an amplifier of the IC KA2203, SN16975, TBA820, UL1482P. Which has 4 Watt power output with 4 Ohm impedance. At least 8 Volt supply voltage and a maximum of 20 volts.Part List
R1 = 100K
R2 = 56R
R3 = 56R
Use 1/2 W resistor
C1 = 47uF
C2 = 100uFC3 = 100uF
C4 = 470uF
C5 = 470pF
C6 = 0.22uF
C7 = 100uF
U1 = KA2203 , SN16975, TBA820, UL1482P
