Received the KIT in a very nice box with everything included. The asembly is straight forward as the values of most of the coponents are printed on the PCB and the rest can be locqted by checking thr photos. The performance of the amp is beyond expectations for this price and the noice is inexistent. Make sure you set the variable trimers in order to get the same -V and +V at the entrance of the audio amp part between 15 and 18 Volts.
