Question about Wurlitzer Jukebox 1015 One More Time 100-Disc CD Changer

Wurlitzer 1015 OMT 100CD

Hi there,
I have a problem with the gripper arm not returning the disc properly into the CD slot on occasion. This problem is not consistent. Some days it happens a lot and other days it may happens once or twice. It is no particlaur CDs or slots is does it with - its all random. When it happens, the CD front end (closest to the carousel spindle) is placed in the preceeding CD's slot. This jams 2 CDs together and so when the unit tried play that same CD or the on eit jammed with, then all hell breaks loose!
This problem started right after I upgraded the CD player unit from a CDM4 to a CDM 12. The upgrade required that I replace the gripper arm (which I think was unneccessary) and believe that's where things went wrong. Otherwise the machine performs well.

    Thanks Dave,

    Will do that but am a bit nervous about it. It seems then the replacement arm might have been a bit bent right from the start. I think maybe I should just then put back the old one - although I'm not looking forward to that - it took me awhile to get the gears alighned properly the last time I did it.

    I will report back once done.



    Thanks again!

    Thanks Dave,

    I will do the lock latch adjustment first and then see what happens.

    Regarding the gripper arm - the one I had for the CDM4 is identical in every way to the one I got as part of the cdm12 upgrade kit - that's why I was confused as to why it had to be replaced. If it is supposed to be different then either they included the wrong arm in the package or the previous owner of the system must have had it replaced before.

    For info - this was a 50CD unit which I first upgraded to 100cd and then upgraded the CD player (the CDM4 was starting to fail). The Juke was manufactured in 1987.

    About the discs not being put properly on the player - I have never managed to set up the CDM12 so that the disc lands 100% on target - it slightly off-centre bu the magnet when it lands on the disc correct the disc into position so wasn't too worried aboit it. I first suspected this was the reason why some discs are not returning correctly but dismissed that thought as the disc position after play is alwasy the same so should have no impact on how the gripper arm lifts it up.

    Thanks again Dave,

    I have replaced the latch bracket. It was part of the upgrade kit. I must say Wurlitzer supllied a very nice and complete package and was easy to follow the instructions.

    I will do the adjustment as discussed, but only over the weekend - work my *** of during the week and too tired to fiddle on the juke in the evenings. Will post a reply in this forum next week to let you and others know if it worked.

    Hi Dave,

    As promised, some feedback:

    I could find no way to further adjust the latch so had to opt for bending the gripper arm. Now that wasn't easy as this is quite a sturdy piece of kit! However I bent it a very slight bit and then ran the machine on auto play for a whopping 48 hours. Not one single disc was misplaced. So problem solved!!

    Thanks for the help!!



    Next issue:

    I want to upgrade my amp to the K99 (170wpc). Does an upgrade kit exist for this? If so what will it cost? I have already upgraded the speakers to handle high power so its just the amp and power transformer that will need to be upgraded now.

    Regards

    Cornel

I asked a Wurlitzer engineer about this problem and he simply said, "Bend it a bit."

Sounds horrible but there is no genuine adjustment. But before doing that, try moving the carousel lock latch (at the 5 oclock position). This is what locks the carousel and determines its position when the correct CD number is reached. If you could ****** or advance it a little it might work.

    The reason the arm needs changing when upgrading the player is because the centre of the CD will not land correctly in the centre of a CDM12 player if you use the original CDM4 gripper arm. (At least that's as I understand it.) It aligns it slightly differently (left or right) when it turns over the CD. If you compare the two players you'll maybe be able to see that the play position is slightly different. So putting the old arm on will probably cause a different problem.







    Dave.

  • Dave Jukebox Apr 22, 2008

    Just a thought. You ALSO need to change the carousel latch bracket because a 100 cd carousel has smaller teeth and the old latch can't stop the carousel exactly right. (That might be the problem!)



    As to the arm. Maybe I am thinking of a CDM2 or earlier. That's why you get an arm with the kit.

    I've never heard of an upgrade kit for the amp. The more powerful amp is a lot bigger physically and has several external speaker options. It may fit the original amp fastenings but I don't know. Wurlitzer no longer sell the OMT with the large amp for some reason.



    As far as I know the larger amp is rather misleading. It is only more Wattage IF you take full advantage of using external speakers. I think the power to the box itself is exactly the same. It's the extra speaker outputs that give it the extra power (though I might be wrong about that.)

    You can actually do your own upgrade by taking the External Out from the R.H. side of the amp (hidden beneath a ribbon cable) and feed that into another amplifier to drive external speakers seperately.

    I'd definitely think about that possibility.

    The power transformer, if we are talking about the same thing, is part of the amplifier unit and power supply so doesn't need upgrading. It's the right capability for the amp it is fitted to.



    Only if you have used your own drop down transformer on a USA machine would the wattage be something to consider.





    Dave.

I own a Wurlitzer 1015 100cd machine that when turned on flashes number 8 , picks up the CD selected, places it on the CD player which does not turn and after a short while returns it back in its slot....


It is a faulty "actuator switch" for the microswitch K7. Look at the base of the gripper .....follow that rod backwards towards the gearbox and you will see a little sticker saying K7. There is a microswitch activated by a 'duckbill' bracket. Either the bracket has slipped or it is broken, or K7 is faulty.
Wait until the cd has been placed back in the carousel then press on K& and if it the carousel rotates to the next selection...there's the problem.
In a new machine there is a Allen key for tightening that bracket.

Wurlitzer Problem


Hello,

A flashing 8 indicates that the gripper arm is not returning to the idle position. It could in fact be returning, but a switch is not operating properly. Feel free to email me for further troubleshooting help. tech@wurlitzer-ohio.com.

I have a 1993 wurlitzer New York, New York jukebox. it has the same inters as a 1015 one more time. the problem i am having is with the cd gripper arm. it will take a cd from the cd carousal and place it...


I would suspect you have a lubrication (or more specifically lack of lubrication) problem. When the gripper arm is over the carrier, pick it up a couple of inches (as it moves to pickup a CD) and drop it. It should snap right back down. If it doesn't, it will not properly pickup and return CDs. You may be able to lubricate it to get it working again. For further information, you may email me, tech@wurlitzer-ohio.com.

WURLITZER OMT CD 100 D picking problem


Hello J.P.,

You need to get the manual for this jukebox.
You have to however confirm what the manufacturer and the model number of this is. The One More Time was made by the following manufacturers:-
Wurlizer, Rowe Ami, Rock Ola, Antique Apperatus and Sound Leisure.
Look for a serial plate on the back of the jukebox in order to get any information.
You can get manuals in the USA from www.victoryglass.com

Hello, I have a problem with WURLITZER 1015 OMT CD 100D. The arm go to pick up the CD, but returns in the same time as it lock the cd in the gripper.Result is the CD is supported on two points instead of 3...


The carousel is locked in position by the latch at the front (about 6 oclock). If the gripper isn't exactly in line with the cd then you need to adjust the latch a bit.

Wurlitzer OMT, takeout arm continues to cycle all the time


There is a white bracket on the far side of the gripper arm which comes loose so it doesn't click the microswitch beneath it. To prove this press o the bracket when the arm is over the cd magazine and it will stop.

OMT Gripper Issue


There's a spring wound round the shaft of the rod that drives the gripper gears. Oil very lightly. The gearbox rotates when it puts the arm back but the arm is held against the driving part by this spring so if it is sticking the arm will not turn over properly even if the drive shaft is doing what it is supposed to.

Dave.
