The 4 1200 seems to have a different setup with another capstan? Off to the side,but the "Dave" trick works a treat on either.
What ever happened to Dave, his YouTube posts were not only educational at times but always entertaining.
I was wondering that myself. His setting the bead video was one of my favourites.
I replied to one of his videos a while back, and mentioned that I hadn't heard from him on the forums. He said something about being busy with other things. JImChuk
