KORG NUTUBE B1 Pre-amp. Nelson Pass presented a pre-amp using the Korg Nutube dual triode. This was built by skilled electrician and its in excellent working condition. Sold as-is - US shipping only, no international.

Im sure if youre looking, you know what this is. These kits are $300 unassembled and are sold out. Its a genuinely great sounding preamp that has no right to be this good for this price. I bought this as a replacement while my preamp was being repaired, but couldve happily lived with it forever. Guaranteed to arrive as pictured and described, with no warranty given or implied, and no returns.

This is a custom built Pass B1 buffer preamp that I DIYd over a year ago.I built this for my lab as a reference preamp and its served well but its time to let it go as Ive found a better preamp for my needs. I built this using the PCB + four JFET package available as PASSDIY.com. The potentiometer is a genuine Alps Blue, and the case is of chinsese origin. The power supply is a Meanwell 18v PSU. The wire used is silver plated teflon. This is a fantastic preamp for someone needing a simple, transparent, and clean buffer between their source component and preamp for optimum signal transfer. If you have a dac with lots of voltage on tap, this is perfect to interface it with a matching amp. Heres an opportunity to own a fantastic preamp at a fraction of the price of the Firstwatt model, despite them being identical. I will not ship this item outside of the United States unless the buyer uses the Ebay International Shipping Program, otherwise the order will be cancelled.
