The figure transistor performance quick test circuit. In the figure, HFC9300is music IC which stores a song. BL is a speaker , S is the trigger switch . VTx is a transistor undertest. When VTx inserts into the socket, and thepin collectorinsertsinto c , the base inserts into b , the emitter inserts into e . If VTx is a good tube, BL will play a beautiful song; if VTx is a bad tube , then BL keeps silence.
