Ineffectual Artifices

Early 1970's Wurlitzer transistor organ into a Koma Elektronik field kit with cv radio.
The speaker output of the Koma field kit is feeding a mid-1970's Leslie model 705 Roto-Sonic rotating speaker.
There is a Philips model EL3752/00 stereo microphone set up in the room near the Leslie cabinet.
The microphone is interfaced to the camera through a Zoom H4 in monitor mode.
