https://www.pcbway.com/ This time I will describe to you how to make a very simple single tube amplifier that also works at low voltage and is powered by 12V DC. Valve amplifiers produce greater amounts of total harmonic distortion, but this type of distortion (2nd harmonic) is not as disturbing to the ear, and is perceived as a "warm pleasant sound", especially when playing instruments where this amplifiers are still indispensable.
Device is very simple to build and consist only a few components:
- PCL82 Vacuum Tube
- DC-DC boost module
- 7815 Voltage stabilizer
- 1M potentiometer
- 220V/6V mains transformer
- and Speaker 3W/4Ohm
The output power is about one watt without unpleasant audible distortions, which is quite sufficient for the purpose for which I built it. Namely, I will use this amplifier in my next simple radio projects as an audio output part. However, with high-sensitivity speakers with a light membrane with a large surface area, this power is quite sufficient for normal listening.
The device is built into a suitable box made of 5mm PVC board and lined with self-adhesive wallpaper, and it also serves as a speaker box.
