I'm not sure if that motor is reversible but in this application it is not. I believe it has brushes - the one I used to own smelled like an old drill motor. There is a large resistor and switches used to slow the speed just as the tonearm starts to lower. Be sure these switches are operating correctly or you will ruin needles and record edges quickly as it slams down.  On Wednesday, February 22, 2023 at 09:37:48 PM EST, Jay Hennigan via Jukebox-list <jukebox-list(a)lists.netlojix.com> wrote: On 2/22/23 16:16, ascott822 via Jukebox-list wrote: Service manuals are available here: https://victoryglass.com/product/part-number-71-1264/ Generally speaking, AC motors with four wires are often reversible. Power is applied to two wires. A capacitor is switched in to the other pair of wires to change directions. Seeburg used this setup for decades. I have no idea about the Mills specifically, but when you get the manual it should help. -- Jay Hennigan - jay(a)west.net Network Engineering - CCIE #7880 503 897-8550 - WB6RDV _______________________________________________ Jukebox-list mailing list -- jukebox-list(a)lists.netlojix.com To unsubscribe send an email to jukebox-list-leave(a)lists.netlojix.com %(web_page_url)slistinfo%(cgiext)s/%(_internal_name)s Searchable Archives: http://jukebox.markmail.org/
