Nice product. I built it in 45min . it looks amazing The sound is very clear and loud. it has good amplification. But it also as a bit off 50Hz humming or buzzing sound from the 12v AC going to the speakers wich is annoying but if you turn the volume up it goes away and the sound is great. It is worth the money and a nice toy to have I like it a lot.
it is a very good stuff...thanks
didnt test but arrived at time and system is good.
Works fine after little modifications.
Ho ricevuto oggi. Non ho ancora provato, ma sono di bell'aspetto. E'ben confezionato. Il circuito stampato e i componenti sembrano di buona qualità.
For this piece to be trully impressive you would have to replace the tubes for so.ething more expensive but for the money I think it is a really nice piece , i recommend replacing blue diodes with light orange or none at all :)
Conforme utilizza 1 transfo alternato da 12 volt
awesome, 3 day come earlier than schedule, but my package lack of potensiometer
Super..
Funziona benissimo, cambiando valvole anche meglio, consigliato
