6BM8 triode connection non-feedback tube amplifier 　design production, circuit diagram, recording 

Low distortion and 1.5W output
A vacuum tube amplifier that uses a 12V AC adapter
We have reduced the number of parts to a minimum
The load resistance of the output transformer is used at 5kΩ.
As a hobby, I design and build vacuum tube amplifiers.
There is a simple explanation of the circuit design process.
The actual sound of this amplifier is recorded and transmitted.
Have fun with subtitles!
