Freshly pro built Dunnington Audio 258D.

It’s an updated take on Don Buchla’s 258 design that modernizes it while retaining its character. The version is incredibly stable and tracks 6 octaves At 1.2v/oct.
My favorite yet simple additional is the v/oct (grey) cv input. Having owned a prior 258, tuning with the attenuators each time was a pain. 

The boards were professionally fabricated and all the surface mount parts soldered on. No expense was spared in the quality of the parts. These units will last for decades to come.

They are fully calibrated and fully tested and ready to go. They come with a 1 year warranty should anything go wrong, but it won’t.
