I have no manual documents to guide how to make it in my package.
The ripple noise is a bit high, the sound quality of course is not comparable to a professional system, but looks cool with the transprent case and it was fun to assemble.
The full and true description of the item. I recommend everyone.
Les haut-parleurs ont été mis sans protection dans le même sachet des composants et visserie , une membrane a failli être percée.
Lipsesc piulitele de fixare a potentiometrelor, foliile de mica izolatoare pentru CI TDA2030A, 2 x Heat shrink tubing. Destul de slabut ca sunet si se incalzeste destul de tare radiatoarele si transformatorul. Potentiometru din mijloc nu pare sa aiba vre-un efect notabil asupra sunetului.
This was give to my grandson to practice electronics ie identifying components, and soldering.... The track lifts and breaks very easily and is a bit of a nightmare. After I fault found the track breaks, it did work, but with a loud hum! which defeats the object. The -15V rail is pulled down to -5VDC and has a 50Hz ripple on it! as the the only the amplifiers and the LED indicator are on this rail, is this the fault of the mains transformer or design?
The product come's with Chinese only documentation. I will not recommend for experienced builder.
Totalmente funcional, tudo chegou como deveria sem destruição. Depois que a construção é executada sem problemas.
Totalmente funcional, mas algumas peças não chegaram e tive de comprá-las. Os alto-falantes foram rompidos.
Well - two resistors had wrong values - used 1 hour to get the protecting paper off the plexi glass. Sound is there but not that good, but ignaff for my lab use. I would probably not by it again , but usable But I can recommend the seller but not this product
