Uni-Syn

["Dr. Carl Rubino" <ruvino@ripnet.com>]

I was going through some boxes of old parts and found my old uni-syn. Havn't
used it in many years and have forgotten how. What I really don't remember is
how to use the internal spring loaded adjustment. Any help to revive my
increasingly impaired memory would be gratefully received.
