As some of you may know I recently bought a new house and just finished moving. A lot of my collection is now in a climate controlled storage facility, but some of the best are now in a display room. That includes this 37-690.
I moved all the sets either myself or with the help of a friend. I removed some of the chassis to lighten the load which gave me the opportunity to finally take a closer look inside this beast.
Turned out the removing the lower chassis didn't help as much as we had hoped but taking out the big speaker too sure did.

While disconnecting the tweeters I noted that they both were nuts and showed evidence of having been removed. Also the cable for the one in the upper right butts up next to a tube shield.
Well that got me thinking and I did a little web searching and discovered ever example I could find showed the tweeters with the connections up top - not at the bottom. That leads me to the conclusion that mine are in upside-down!
