NP-100v12 - 12au7 / MosFET Headphone Amp
DIY 12AU7 (ECC82) Tube / IRF510 MOSFET Headphone Amplifier
The NP-100v12 is a simple headphone amplifier that allows an entry level builder to experience assembling and listening to their own creation. I use the term builder as electronic experience combined with innovation which allows the creation of a device, rather than simple board stuffing. This amplifier can take on many shapes and sizes; I especially like when builders reuse older devices as cases and even recycle some components from various discarded power supplies. I try to keep price at a minimum because this amplifier is very basic and allows the builder to seek out theory, and actually “listen” to their music, and grow to build more complex projects in the future.
