How Auto Speed Works 1968 Seeburg LS2 Gem Jukebox

Not all 7 inch vinyl records are 45's. Some are 33 1/3 RPM like the big LP's. Some Seeburg Jukeboxes like this "1968 LS2 Gem" came standard with the Auto Speed Unit which allowed both records to be played. Some Seeburg models had the Auto Speed as an optional purchase. This video shows you how the Seeburg Jukebox Mechanism knows which "hole size" record is being played and the switch that activates the auto-speed unit.
I am not a Seeburg Mechanic nor Expert. If you are troubleshooting your Seeburg, there is a very good section of the manual explaining the Auto Speed Unit. The manual explains how to use a Seeburg Strobe Disk to adjust the Auto Speed Unit if necessary. Since you don't have a strobe disk, you can download a paper copy jpg from the Seeburg Yahoo group and adhere the paper strobe disc to an old 45.
Sidebar note: Some 7" vinyl records with small holes are 45 RPM not 33 1/3. Enlarging the hole to 45 size is called "dinking" which works but reduces the $ value if you choose to sell the record (and most jukebox played 7" records are worth squat anyway).
Let me know if you found this video useful.

Most of my 45's have a small hole which meana this switch has to be by-passed

I enjoyed it but would love to have seen the 33/45 shift

Very informative how hard is it to find 33 7" records I just recently was given a Seeburg model ss160 that is capable of playing 33 lps. It needs a good cleaning and service, after watching a few you tube videos I think its above my knowledge, any idea what servicing a unit like this would cost? It lights up and turns on.
