[BC] Oldest Transmitter still in daily service

[AM Lover]

I love the old transmitters the best, nothing beats the warm glow of tubes.  And the light company loves the power consumption as well.

I was wondering what the oldest transmitter any of you still know of in daily service in the USA might be?  I know of at least one collins21e still online as the main transmitter, thats only going back to 1961 or so, surely someone still has an old old transmitter still running.  I know of a tv station that was still running old G E transmitters last time i checked, one went way back in time to the 1950s when it was installed USED and still runs everyday or did a couple years ago........but what about am/fm?


I would love to hear of any pre 1965 transmitters still running daily.
