A look at the Columbia 109's insides, and Garrard motor

Hi, I am watching your very informative, yet entertaining videos with pleasure. I did get bitten by charm of mechanical gramophones bug some years ago, and as you probably know - it escalates :-) Thank you for sharing your knowledge with rest of the World. I learned (and still am) a lot from your amazing channel! I am wondering why you never did any video about Brunswick? Greetings from Chicago! Art

Brunswick, and Columbia, and there are several other makes of records from the teens an d into the early twenties played at 80 rpm. Path'e records which were vertical also played at 80. 78 did not become the standard speed for records until about late 1925 or so, that is what I have read.
