Record rejects as needle lands

[junkinbarry]

Hello Ron, brought the 201 back to my home shop today. Replaced the smoothing rectifier , but no change. I’m really not sure what to try next. Thanks for your help. Barry

Hi Barry,
If the 2050 fires when you plug the mech plug in--that indicates that the "reject pin {#3}" {cancel circuit}, on that plug, is somehow "grounded".
You will need to find/correct that situation-- Ron Rich

Ron, I clipped the wire to pin 3 on the 657 11 pin plug (black/ white wire). No change. Thanks again, Barry

Barry,
Are you 200% sure the tube is not firing, with the mech unplugged ? Try a new 2050 ??

Hi Barry,
OK--Look at the socket side--is that pin grounded (possible the remote cancel switch is closed ??

Ok Ron, the 2050 would fire as soon as the 6 pin mech plug was inserted, not the 11 pin. After clipping the trip wire I decided to take another look at the receiver. In the process of checking every component, I found a bad solder connection on the negative side of the bridge rectifier. Re soldered connection and problem solved. Thanks for all of your help. This is just a hobby, but it can get stressful when a friend spends money on components and you let them down. Thanks again, Barry

Hi Barry,
Glad you found it !

Hi Ron!

I'm a complete newbie when it comes to Jukeboxes and one the guys in my garage has a Seeburg LS1 with this exact symptom and asked me to take a look at it. 

I can hear the double click from the popularity meter, so it indicates that it's an electrical problem. I have measured the tone arm reject switch by manually turning the motor until the needle hits the record and there is no short from the switch, only before play mode and at the end of the record if i manually move the tone arm towards the end of record position I get the short.

I have tried removing the cables to the reject switch but i get the same instant reject behaviour, is this what's supposed to happen or should a shorted reject switch being disconnected make the record play?

By detent release lever, do you mean the release lever that you can lift up to switch the clutch from scan mode to play mode? I have not tried to hold it down yet to see if the records continues to play instead of immediately rejecting, i did however try to hold it up which causes it to get stuck in a loop loading and then reject the same record over and over.

Also, what do you mean by a spark arresting cap on the series of switches?

I apologize-- there was a glaring error in that quote--I wrote the word "electrical", where I should have said "mechanical". it has been fixed--please re-read it. Please read your service manual, for the terms used here. a "spark arresting cap" is just that, Normally used on an AC switch, it prevents "spark(ing)". Usually in a Seeburg, it was a .01--- Ron Rich

Ah ok thank you, so then it's most likely a mechanical problem then. I've read the service manual but can't find anywhere where it says "detent release lever", only release lever, is this the same thing? I tried holding this one down but it makes no difference, record is still rejecting after needle touch, and holding it up creates a loop where it loads then reject forever.

That's the Detent/trip, Release Lever. Ron Rich

Thank you, and since pressing this down during transfer to play mode does nothing and the record still rejects when the needle hits it should be a mechanical problem then? Do you have any recommendation how i should go ahead to figure out what mechanical area is causing this problem?

[Ron Rich]

Yes-sir--My "suggestion" would be--Purchase a copy of my "Seeburg Mechanism Guide", as I covered that in detail there. Should you wish, contact me at: [e-mail] Ron Rich

Did some more testing, manually pressing down the clutch shifting lever on the opposite side of the release lever makes the record start playing, otherwise it just seem to skip over the play notch in on the clutch shifting cam. Releasing the release lever won't however stop playing the record, i need to manually fiddle around with the Worm on the clutch it seems, turn it by hand for a while, to make it go to transfer more and stop playing the record.



I tried doing the clutch 1,2,3,4 adjustments, same issue though.

Your clutch yoke pin is frozen to the yoke, and or to the detent #2 lever, or the clutch yoke (long) pin block support, has come lose. Ron Rich
