Clayton, I realize I have only now 'discovered' your post online about your Rangaire, but would sure be interested is knowing if you have a manual? I have a Rangaire Intercom with AM/FM Stereo and Phonograph (sounds like you may have the same). Our home has speakers for it in six rooms, but has never worked. We are interested in getting it checked out, and hopefully, we will be able to use it! It has been suggested to us that it may just need a new tube(s), or could be the wiring between rooms. If you have a manual for your system, would you be willing to email me a copy of it? I would greatly appreciate it, if this is possible. Thank you!! Joe
