    For Sale
    Selling a freshly built Korg Nutube Headphone Amplifier.  The Korg Nutube 6P1 is based on vacuum fluorescent display technology to create a very low power triode tube.  The PCB design is by Pete Millett, full details on the amplifier design can be found here http://www.pmillett.com/nuhybrid.html
    Upgrades over the default build are as follows,
    -Elna SILMIC II and WIMA Polypropylene capacitors in the audio path
    -Gold Plated headphone jack and opamp sockets
    -Vishay DALE RN series resistors used throughout
    As this is a brand new design Pete discovered an issue using the original 2N7000 transistors and changed the design to use 2N3904 instead. This change has been implemented in this amplifier so it is fully up to date.
    In place of the default plastic enclosure and DC power brick this amplifier has been built into a brushed aluminium enclosure with a mains power transformer and Linear Regulated power supply.
    Any questions please ask...
