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.
I received today. I don't still tested, but they are good appearance. It's good packaged. The circuit board and components looks good quality.
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 :)
Compliant uses 1 alternating 12 volt transfo
