Seeburg pin bank trouble shooting

Finish rounded smooth edges should be facing the magnet

Hey Duke--
Ain't that whut I done rit a-fore?? 'Bout 5-6 posts ago ??
Ron Rich

Yes sorry I was doing this from a smart phone at a big function

Duke,
No problem !! But, in this case, I think you should either spank that phone, for being stupid, or take it back, 'cause it ain't smart ??
Or--maybe it's a male phone, that suffers the same problem as most women claim all males do--inability to "double task" ??

Hey Ron,

So I did some fishing through the service manual and I came across one of the issues and that was the contact block which was out of alignment with the pin bank which can cause problems. The manual tells you to get the mech into the A1 play position and have the A2 pin in the selected position as well. Then you loosen the two screws below the assembly and slide it so that both A1 and A2 pins are centered in between the two frogs which are off set from each other. Once accomplishing this then you go down to the K9/K10 selections and do the same thing. Here in lies the problem that I am having and I did not see and adjustment that I could make to correct the problem. I drew a picture on a yellow sticky note showing how I had positioned the pins in between the two frogs. Despite the K10 pin being centered in between the two frogs when the mech scans the K 10 pin when in the play position is not aligned with the center of the frog itself so it misses the metal tip of the frog and will keep scanning as the cone shape of the frog pushes the pin inward from the play position but not far enough to kill the selection completely. It will scan once more and then the fully metal cone will cancel the selection.

I have attached thee pictures

Photo 1 is the A1 and A2 pins centered between the two frogs and perfectly aligned with the tips of the frogs when in the play position

Photo 2 is the K9 and K10 pins. Both pins are centered between the frogs as the service manual calls for but notice how the K10 pin (the far one) is not aligned properly with the metal tip of the frog… it appears as if it is in the non play position when it is really in fact engaged.

Photo 3 is the diagram that I drew demonstrating that the pins are centered between the two frogs but the K10 pin unlike the K9 pin is not aligned with the metal tip in the center of the frog.

Hope that this gives you enough detail.

Thanks

Don

Duke,
You gots me connfuzzed--
What's generally referred to as a "Frog", is the whole contact block assembly, on accounta, because, it "looks like a frog", in the model A phonographs--
It contains a cancel coil assembly, a "dressing pin" and a sensor for each side of the record. It's anchored to the mechanism via two screws, that have slotted holes for minor adjusting. It is ( or should be) inside a "U-shaped", spring loaded, bracket that pushes it in both directions.
If you can use the terms in the manual, it might help to solve your problem.

Hey Ron,

Sorry for the confusion but i am attaching a picture from the maunal that I think will give you an idea of what I am talking about.

If you look at the diagram attached you will see the center line which centers the pins between the left and right contacts. This center line has been established. I made the adjustment yesterday.

You will notice the tip of a pen in the picture. This is to show where the A2 or in my case the K10 pin sits when in the play position (the A2 position is just fine). The tip of my pen which simulates where the the pin is now. It should however when in the play position be lined up with the "R" pointing with an arrow towards the middle of the right contact in the diagram.

I have not found an adjustment for this.

Thanks

Don

Don,
The reason you don't "find an adjustment", is that there is, NO, "adjustment", for this "problem"--the pin is either installed backwards, and, or bent, or both ! To repair this, correctly, the pin needs to be removed, flattened,, and re-installed correctly, or, be replaced-- Ron Rich

Well Ron,

Wouldn't you know it. the pin was bent in the slightest bit. I carefully took a small flat head and put a little pressure on the pin in the play position and everything works! It's still not 100 percent centered on the contact but I can't imagine all of them are 100 percent perfect. Thanks for your insight and patience.

Don

Hi Don,
No problem--glad you fund it !
