This is a Bauer FB-5000J transmitter, stashed away in the corner of a transmitter site.
Sorry I can’t get a better angle on it, as I said, it is stuck in the corner.
I don’t know what vintage it is, it seems to be from the early 1960s or so as it has a low serial number. It ran as the main transmitter until the Harris Gates BC5H was installed in 1976. The transmitter is in beautiful shape, almost a museum piece. I don’t know if it still has all its original iron, as the modulation transformer may have contained PCBs and been disposed of. Otherwise, it is complete and tuned to 1,460 kHz.
I think the owner might be willing to donate it to a reputable organization, preferably a 501(c)(3).
