Don't let me stop you waiting for Marty's futher guidance - but there are a couple of points that I would like to make meantime.
Firstly, before you carried out the modification to disable it, your automix wasn't working. You told us that in another thread (462) although you appear to have deleted that first post. That could well be complicating what you are now faced with.
Secondly, don't let removing the turntable assy intimidate you, it only looks complex because of the automix. If the automix wasn't there, it would, in simple terms, be a plate with the platter and motor - four fixings to remove, unplug the motor and it's out! The only extra you have to deal with is the drive rod that you've marked 4 in your picture above. Also I can't see the fourth fixing in your picture but it's probably there, just hidden.
Norman.

I might be able to give you more guidance, but first I need to look at a Rock-Ola mechanism. Unfortunately, I won't have access to one for at least a few days. Let me know if you find a solution in the meantime, so I don't go out of my way. Marty, much appreciated. If it helps, I just found a photo of what the bottom of the plate is supposed to look like. From what I can tell, these are the locations of the same items I labelled above 1. Lifter Bracket (not visible but on the other side) 2. The bottom lip of the Lifter Bracket 3. This is the piece that's currently being blocked by #2 (not visible but on the other side) 4. The Drive Shaft. We can see how the drive shaft ends up moving Piece #3 from this beneath view. If you watch this video of what's supposed to happen after normal play (start around 4:15), whenever the tonearm is returning to base, it triggers a mechanism that pops the Lifter Bracket back up. Alas, I've been staring at photo of the bottom of the plate and I can't figure out what's holding the Lifter Bracket down in place. There's no top side mechanism I can see that's holding it down. I can't tell if the Drive Shaft is directly connected to the Lifter mechanism or not. Either way, winding the drive shaft and gripper arm back to the carousel doesn't release the Lifter Bracket, regardless. Something else is still holding it down.  |

I'm beginning to believe that that your parts (2 & 3) just got crossed up and may need some "gentle persuasion" to get the into their proper positions.

I'm beginning to believe that that your parts (2 & 3) just got crossed up and may need some "gentle persuasion" to get the into their proper positions. I had a similar thought but forcing Part #2 (the bottom lip of the Lifter) out of the groove to allow Part #3 to slide past requires more force than I'm comfortable with trying. I don't want to make things worse by breaking the part itself and unfortunately, Part #2 is deep enough that trying to pry it higher risks breaking the entire bracket. I'm still trying to figure out how the release mechanism works. Watching this video, I can see what's supposed to happen: youtu.be/niKYU2X03yw?t=265 (go to 4:25 if it doesn't open there automatically). It looks as if the Drive Rod/Shaft could raise the Lifter but I've already tried to manually wind the gripper back, which does move the Drive Shaft a little but not enough to pop the Lifter back up and out of the way. |

Hi Norman: the only problem I had with the automix before was that I didn't know how to safely remove the assembly but as it turns out, it was literally as simple as popping off the "E-Clip" and pulling the assembly off. I deleted that previous post once I figured out what I did wrong. The automix did work however. The only reason I removed the assembly is because I have small-hole 7"s that play at 45 rpm and the only way to use them in the jukebox was to remove the assembly. Meanwhile, any suggestions on how to remove the Drive Rod? I think if I can remove that temporarily, it'd help to reset the Lifter Bracket back in its proper position. |

There's a clip on the end, just remove it and the drive rod will slip off whichever end you decide! Rock-Ola call it a "keeper" and you just pry it open. You seem to have a good understanding of how the automix operates - for the life of me, I cannot understand why you don't remove the turntable assy.! You can see from the picture that you posted above of the underside, all that's missing from it is the turntable motor.

Norman: the reason I don't want to try to remove the assembly is because I (clearly!) don't have much experience working with my jukebox and in general, I'm just not that "mechanically inclined." Doesn't mean I'm not open to learning but given that I got myself into this situation by doing nothing more than pressing down on a single part, I feel like disassembling and reassembling the turntable platform would increase the likelihood of me making things even worse. That said, I'll definitely keep your suggestion in mind as I very slowly troubleshoot this. Under other circumstances, I'd call in the repair person who serviced the machine to begin with but I'd like to wait until I have at least one other "fix" for him to work on (replacing the program glass). |

12/23 update:
So basically, I'm an idiot .
To make a long story short, after detaching the drive rod from the gripper motor — as many suggested — I still couldn't get the Lifter Bracket to pop back up and in trying to figure out its mechanism, the Bracket popped back up.
As it turns out, the Bracket wasn't being held down mechanically. It was simply stuck — as in "sticky" — and by lifting the prongs in the right way, I freed it.
So all this time, all I needed to do was just jostle the Bracket prongs to get it un-stuck.
Oops.
In my "defense": this is all new to me and I'm generally not mechanically-inclined (clearly!) so a lot of trial and error was going to be invovled regardless but god, do I feel dumb this morning.
On the upside, my jukebox works again. Happy holidays to me!
