Hi Bill,
Yeah, I figured Yahoo Groups was still active, if limping along. I had a profile for years that became impossible to manage after several changes of primary email addresses, redirects, etc.; but I still get email notifications from a local Astronomical Society Yahoo Group. So, even when you think you've shut down your profile, Yahoo continues on autopilot.
Even with the security risks associated with the Groups, I may actually have to see if I can reactivate my profile and register for the Allison group.
As I indicated, I put the CD-7's "in the shop" so to speak. Texasound will likely take a week or two to get to them. I didn't take detailed pictures of the tweeters before I dropped them off, and what few pictures I have I will need to resize down to the lower quality supported by this forum. I tried uploading a couple with my original post, but hit that 200MB limit immediately.
I had posted pics to Reddit and to a local Austin Audiophile group page on Facebook. I don't know if this forum permits redirection links, but I'll see if I can add them.
Otherwise you might need to wait a week or two for detailed pics of the tweets.
Many thanks, austingonzo.
