I retire my Nak BX300 years ago but plan to revive it with new rubber at some point. I used it as a mixdown deck in my little analog studio (the final version of the "porta studio" Teac 8 track with DBX) for years as well as a main component of my hifi rig. Dolby C is amazingly effective in this 3 head deck, and the thing is built like a tank...a beautiful sounding deck.
