It uses a pair of flags to detect the size of the record as it drops. If the record hit the flag at the base of the tonearm and the flag near the platter, it knows it's playing a 12" record. If the record only hits the flag near the platter, it knows it's playing a 10" record. And if the record doesn't touch either flag, then it knows it's playing a 7" record -- at least if everything is working correctly.
Ok, I figured out what you meant - the record strikes the flag as it drops, sets it to 12” - if the flag is NOT struck, it defaults to 10” (typical 78RPM size). In that case, everything is working properly!
If you go back to 7:47, you will notice 4 'steps' on the motor shaft, this is how the speed selection works, the idler goes up and down depending on what speed is selected. Motor runs at a constant speed, just the gear ratio changes.
Hello, enjoyed your videos. I have a similar record player to this. Motorola model 8H27W-1, looks like was made 8/22/1959. My problem is with the volume control, when you turn the knob sound is low or not coming out of front speakers. It was but then would fade in and out and then if wiggle knob it would get lounder. Now even wiggling does not do anything. I took bottom cover off of player off so can see inside, I can see where volume knob is coming through to make connection, but don't know much more of what to look for or do, any ideas? I don't see anywhere here to add a photo that would help. EDIT: I got it working!!! Your video was so helpful to take the turntable out and I think just the wire that plugs into the speaker port was it. When I put it back together and played a record I only have it on volume 2 and it is great! There are some other issues similar to yours with the record finding the right spot to sit at, but I am just going to leave that alone and enjoy listening. Thanks, will keep watching for any further Motorola videos.

Ah, ok… that makes no sense… if a standard LP is 12”, that flag never gets touched - just the button on the deck - and it starts in the correct spot

I tested it using my hand and sure enough…
You don't have to take off the clips which hold it in. Just press until they are vertical and the unit lifts straight up.

Did I not explain this? I thought I did...

It definitely wasn't heavily used...
I can't understand why Motorola used a 2 Pole motor. I know voice of music made a 4 Pole
Cost savings?
Voice of Music never used a four pole motor
OK - I may have misspoken.
They list a four pole in the catalog for record players meant to be used with magnetic cartridges. Not cheap.
Also, their professional series.
