Just one screw (if any) hold the frequency generator in, just put it in the one you're using.

The 118A frequency generator is held to its special bracket with three machine screws. The bracket that fits into the 551B is quite different from the bracket that fits into the 551C. It is not merely a case of unscrewing/screwing. It's actually easier just to use a long tie-wrap or two to secure them, regardless of the KSU type. It's a moot point, since you will have more luck finding a Duesenberg in your neighbor's barn than finding the bracket. They are made of Evaporatum/Rapidium.

Thank you for all your comments. I am going to sign off until I get more of the 25-pair wire run. I did find a Valcom V-119RT 19 station intercom, a Melco KA-380 paging access, and a Valcom FM tuner, none of which I remember that I had. One of my goals was to hook up the extra 760 speakers that I had to some sort of paging system. I think I hinted at that in a previous post. Anyway, will keep searching.

Can someone please post a picture or link of a 551C.

Thanks.

I'm not computer literate enough to post an image of mine to this site, but if you give me your email, I can send you a photo.

Thank You for the picture of the "Four Banger or Lunchbox". We had nicknames for the smaller units and never did call them by their proper names or numbers. A picture is worth a thousand fuzzy memories.
