[GreenKeys] Need ASR33 repair help, in Ann Arbor MI

[drlegendre .]

Wayne,

For those of us not in-the-know, could you briefly explain the function of
the 'distributor' in these machines? Is this a mechanical rotary contactor,
the likes of an automotive distributor - less the spark gap, of course?
Does it use carbon brushes / wipers and so forth?

@All

How the +HECK+ do you reply in-thread to a greenkeys post? I'm used to
communicating with other lists via gmail, where if I hit the 'Reply' field,
it sends my reply to the list, and properly threads it. With greenkeys. my
replies always go directly, and personally to the last poster - rather than
the list et al.

If you're seeing this post, it's because I tacked a greenkeys reply to the
To: field in the mail, which is actually pointed to Wayne / Teletypeparts.
Are you all seeing this, properly threaded? If not, how do I handle this
properly via gmail?

I can only imagine the duplicate threads and other havoc my alleged
contributions might be creating. Thank you for your deference on this
occasion of my newbishness. ;-)
