This study aimed to determine the feasibility level of the trainer troubleshooting audio amplifier as a learning media in PPPAV subject. The method used in this study is Research and Development (R&D) with the data collected by interview and questionnaires. This study was developed trainer with acrylic box size 50 cm × 40 cm × 20 cm which divided to troubleshooting switch, solution switch, test point, input and power. The results showed that the feasibility rate was 91,25%, validated by two learning media experts and the guidebook was 90,21%. Those scores are categorized as very decent. A good response was received from 33 vocational high school students who had tried, with an average score of 85,51%. They are classified in a very decent category.
