Congrats on the find, Bruce. That makes 3 of them I'm aware of. Wonder
if you got a manual with yours? If not, let me know and I can put you
in touch with a fellow who offers a decent copy for under $10 shipped.

I'll have to check again, but I think mine has the same stamp on the
back of the speaker panel. I figured it was an RCA QC stamp of some
sort, but perhaps not? Wonder too, if perhaps your receiver was indeed
used in a tower with the added switch being used for an outside
speaker to an observation deck. Such decks were quite common back
then, a few smaller/older airports still have them today.

Would be interested in seeing any photos you have, and happy to send
you some shots from this side as well. Did yours come in the RCA tower
rack cabinet or as separate units?
