Low Sound Output in Experimental IRFZ24N Mosfet Amplifier Circuit: Possible Reasons?

The discussion revolves around a user's experience with a circuit using the IRFZ24N MOSFET, which exhibits low sound output when an audio signal is connected. Initial responses suggest that the circuit design may be inadequate, as a single resistor is insufficient for proper operation. The user notes that touching the MOSFET gate produces a significant hum, indicating potential grounding or circuit design issues. Further inquiries highlight the absence of capacitors and the need for a proper power supply voltage. Comparisons are made between the behavior of MOSFETs and bipolar junction transistors (BJTs), with emphasis on the differences in their operation and resulting audio output.
