    dbt=dim bulb tester, easy to build
    as i mentionned earlier my 737 was clicking on and off repeatedly, so i changed few transistors on protection board and also all caps on that board, maybe some on the power supply one as well but i did not change anything on the AWH-033 one

    Hi, recaping and changig the transistors on protection board solved the problem. I have 2 sx-737 : silver face and black face, i have only recaped the silver one.
