This is where I'll be tracking the build of the headphone tube amp. More documentation on jpreardon.com
- The NP-100v12: 12AU7 (ECC82) / IRF510 Headphone Amp was referenced on this instructable. This one seems to be pretty simple, only uses one tube and may be a great project to start with.
- Starving Student Apparently the 19J6 tubes are a bit harder to come by than some others. There are some modifications that use more readily available tubes though. There is also a warning about this amp potentially frying two types of DACs.
- Millett MAX (more info at diyforums) Both the Millett Max amps have higher part counts than the previously listed amps.
