Top Features

  • This is DIY KIT,you need to solder it by yourself.
  • Installation: According to the component model written in circuit board to install,all components have been writed parameter,Note that two kinds of transistors do not weld wrong.
  • As it is very easy to assemble,so there is no additonal assemble instructions,Please note that before you place the order.
  • Let's DIY and have fun
  • Power supply requirement: Dual 12V-AC,so you need to prepare a transformer (110V to AC 12V*2).Two separate 12V AC transformers work fine when in series connection.
