Tell us about yourself!
Something doesn't quite add up here. I'm using the NTE196 transistor, that brand's equivalent to the TIP31. The problem is that not one device I have puts out the requisite voltage through the headphone jack. It works fine if I manually apply a battery across the base and emitter but a headphone jack doesn't put that much out even with volume cranked all the way up. What are you plugging this into?
