Hey! I'm selling off projects that, due to situation, I can't finish. 20 EUR + shipping from Lithuania

I have: a sturdy metal case with two sockets for 9-pin tubes, a ready-made boost converter board, a jack, and a potentiometer.

I planned to build a low-power amplifier running on low voltage (12V). I can recommend a circuit, or you can choose one yourself.

Can equip by transformer which I planned to use as output - +10EUR
