Two 6-volt batteries One NPN transistor—models 2N2222 or 2N3403 recommended (Radio Shack catalog # 276-1617 is a package of fifteen NPN transistors ideal for this and other experiments) One 100 kΩ resistor One 560 Ω resistor One light-emitting diode (Radio Shack catalog # 276-026 or equivalent ... The maximum rating for the 2N3904 is 625mW, so no surprise that the transistor gets hot fast. If you drop a TIP41C into the circuit you should still be able to measure a signal at the amplifier output, but it will probably a lot lower because the current gain of the TIP41C is a magnitude lower compared to the 2N3904.
