2BOX (alias "tubox")

 

 

2BOX is an home-made audio power amplifier made by using a single vacuum tube (PCL86), two 12V transformers for doorbells and some other surplus components. The whole circuit has been mounted into a box for decoupage, including the loudspeaker. The related photo gallery is available HERE.

 

2BOX è un amplificatore audio "fatto in casa" utilizzando una singola valvola (PCL86), due trasformatori da 12V per campanelli e qualche altro componente di recupero. L'intero circuito è stato montato all'interno di una scatola per decoupage, incluso l'altoparlante. La relativa galleria fotografica è disponibile cliccando QUI.
