DIY Simple PCL82 Low Voltage (12V) Tube Amplifier
https://maker.pro/analog/projects/diy-simple-pcl82-low-voltage-12v-tube-amplifier
How to make a very simple single tube amplifier that also works at low voltage and is powered by 12V DC. Also, instead of an output audio transformer, a standard 220V/6V mains transformer is used.
