Now about the subj. Device is not bad. I was especially pleased with the picture on the screen. Judging by the goat on the sea bank, this is from the fairy tale "Sister Alyonushka and Brother Ivanushka" ?
Amplifier on PAM8403?
And how was the inscription and logo made on the case? Drawn? Cut through? "Выжигатель", maybe (wood burning)?
