Those needing documentation for the Conn Strobotuner ST-6 and ST-11 can
find it on my personal web site:  http://www.mts.net/~smythe/conn.htm

I'm not in the business of selling, servicing or repairing these
instruments.  I just happen to have a serviceable ST-6 that I have been
happily using for the past 20+ years, and its documentation came with
it.

I've simply noted over the years numerous messages on the 'Net seeking
this documentation.  Some years back, in the interests of trying to be
helpful, I scanned my ST-6 documentation and posted it on my web site.
Since then, somebody else sent me the documentation for the ST-11 which
I have also posted.

The ST-6 is nearly identical to the ST-4, ST-5, and ST-8 Strobotuners,
so I would expect the documentation for the ST-6 to reasonably apply to
the others.  I'm uncertain if that statement applies to the schematic
diagram.

Hope this helps a little.
