Thought I'd split this away from the BLJ thread and see if any discussion ensues.
Wow! That seems to be a PA system. Microphone (parabolic) with a power amp (tube) and speaker (megaphone). Not hard to imagine the radical political activists of those times using such a PA. And also not that hard to imagine many of those of whom we have recordings, especially the more urban based (Chicago, St. Louis, Memphis) also having the occasional experience with a PA. In particular the many obvious "advertisement" blues, as by Sleepy John, might hint at promotional concerts with a PA.
That's pretty interesting. Hadn't thought about that. Does anyone else have any hard information about known usage of a PA in pre-war times?
I wonder if there are fora (or even just one) where we might find early electronics geeks who would have this info, yet no awareness that it might be of interest to others. You know, like us.
All for now.
