Pot #1 (P1) is a simple voltage-divider volume control. An audio-taper pot is best for the volume. Pot #2 (P2) sets the bias, and effects the overall character of the output. Playing with it changes the gain, and the compression level, too. A linear-taper pot works well for the bias.

The power supply part consists of a 12V source of DC voltage, which is then increased to 40V through the DC-DC Boost Module, which is needed to power the Tube anode. The heating voltage of this lamp is 16V/300mA and is obtained at the output of the 7815 Voltage Stabilizer using the diode. An interesting option is if we have 16V at the input of.

Low-voltage vacuum tube amplifier design. Amateur radio HF frequency amplifiers using transistors commonly can be powered with around 12 to 14 VDC, or even lower voltages, for QRP transmitters. Tube amplifiers seem to require DC power supplies outputting several hundred volts. For HF (3 to 30 MHz) RF amplification, what limits the power output.

This part is the heart of the amplifier, the PCL82 tube which consists of a triode and a pentode, plus two resistors and a capacitor. Instead of PCL82, without any change in the schematic, ECL82 can be used, in which case the heating voltage should be 6.3 volts. And finally, the output part, which consists of an audio transformer taken out of.

To successfully match the high-voltage, low-current source to the low-voltage, high-current load, we must use a step-down transformer. Since the vacuum tube circuit's Thevenin resistance ranges in the tens of thousands of ohms, and the speaker only has about 8 ohms impedance, we will need a transformer with an impedance ratio of about 10,000:1.
