The recording machines were just the same RCA Electrolas with a weight
slipped over the top of the horseshoe reproducer. The angle would be
the same as any other player, maybe 15 degrees off vertical. I don't
know anythinga about a yellow shaft needle, only the red. The
instructions only mention the red for both recording and playback.
