【ピコの電子工作】9V電池2個で動く！ 超簡単２球真空管アンプ 負帰還回路 6DZ4 三極管

This is a simple two-tube vacuum tube amplifier circuit that runs on two 9V batteries, aimed at beginners in electronics.

I will not go into detail about the characteristics of vacuum tubes.

It does not amplify much, but

I hope it will be a useful hint or clue for those who want to use vacuum tubes for the first time.

If you have any suggestions, please let me know in the comments.
