KORG Nutube Evaluation Board II NEB-2 (Bonus 12V AC Adapter)

■ About the Product
This is the second generation evaluation board (NEB-2) equipped with KORG's next-generation vacuum tube Nutube 6P1, purchased from Akizuki Denshi. I bought it out of curiosity about the sound of vacuum tubes and enjoyed its rich harmonics, so I'm selling it as I organize my equipment.

■ About the Extras

12V Adapter: An AC adapter, which is normally sold separately, is included.

Generic RCA Jacks and Questionable Cables: (Not trash) Only enough for mono, so please use them only if you know what they are. If you don't know, please dispose of them as they'll hurt if you step on them.

Orange Capacitor: One capacitor found at the bottom of my junk box, labeled CDE 715P 600V 223J (1617), is included. It seems to be manufactured in the 17th week of 2016... Could it be useful for guitar tone circuits or modifications? Maybe for humbuckers? I'm not sure. If you're knowledgeable, please make good use of it. As usual, if you don't know what it is, please dispose of it as it will hurt if you step on it.

■ Condition and Documentation
Used only a few times indoors, operation confirmed.

Documentation: Available for download on the Akizuki and KORG websites.
