I found this promotional picture in an old NAB conference technical papers book dating to 1969:

So here we see an obviously qualified and appropriately dressed technician gesturing to all the components she is about to install in the transmitter behind her. I wish I worked there. No, wait, I wish I had that transmitter and perhaps this fetching young woman would come and work at my station. Well, hell, I don’t need a TV transmitter, just the woman.
Sigh.
I wonder how many of these rigs RCA sold before the broadcast division went out of business.
By way of reference, the RCA TT-30FL is a VHF television transmitter, 30 KW peak visual power, 7.5 KW peak audio power, air-cooled.
