nomenclature for Seeburg ds100 mechanism switch
by bpoldstyle＠yahoo.com 28 Sep '25

28 Sep '25

Hi all, My cousin has a Seeburg DS100. He asked for my help identifying a broken part on the mechanism. He said it's a contact switch with a roller on the bottom right hand side of the mech. Apparently the switch is activated when it rolls up the ramp on the right hand side. The roller on that switch has broken off. I'm assuming that switch is replaceable but I have no idea what it is called. I do not have that particular part manual to look it up. I would really appreciate it if anyone is able to provide me with the name or part number of that switch. Thank you, Bruce

Rockola 418 Blowing 28V Fuse
by mboessen＠ktis.net 23 Sep '25

23 Sep '25

Hi, All: Praise the good Lord, I might have found it. Since most folks agreed that the problem had to be that #2 micro switch, and given that I have replaced it twice, I pulled out the wiring diagram and my erasable color pencils and went to work, starting at the common of that #2 switch. Wowsers. The blue-red wire from the common of that switch goes ALL OVER the set, through, I think, SEVEN plugs and 6 cables. I got a little 6v 150 ma test light, hooked it on that common pin and chased it one plug at a time. I believe, when the dust all settles, that it was the white, 6 pin cable going from the control box to the write-in assy that was the culprit. The male side to the write-in chassis where the blue-red wire connects was a little cock-eyed in the plug. That said, I went over every plug that thing passes through, cleaned and sprung the male contacts, and put them back together. I also put some more effort into cleaning the contacts on all the relays in the control box, got my leaf tools and made sure they all had good travel and wiping action. It has been playing for about 3 hours now. I think I've run about 60 selections. Got a little reminder lesson from a thing my grandfather used to say about not fooling with things unnecessarily. I decided to clean all the plugs. Apparently when I plugged that green plug together on the cable that goes from the selector to the A/B snap switches that I jimmied one of those pins, as the selector started intermittently not seeing selected levers. Or maybe it was just oxidized. Anyhow, I believe I have that fixed satisfactorily also. Appreciate the help from you guys. Pretty sure it is the worst jukebox problem I've ever encountered. I think it's been 3 years, 3 service calls and 2 trips to my shop, but hopefully it's finally over!! Best Mike

Seeburg M100A Write-in Issue
by aburkhart＠unilect.com 21 Sep '25

21 Sep '25

On a Seeburg Model 100A, would the absence of the 2050 tube in the Wired Selection Receiver prevent write-in to the solenoid assembly? I am not using wall boxes. My memory was thinking that the 2050 tube was only needed if wall boxes were used. Looking at the schematic, it seems the 2050 tube is always needed on this model - and I don't have one, and my solenoid assembly does not get energized for write-ins. Everything else is working. Am I correct or do I need to follow a different path to solve my problem? Andrew

AMI Motor Dead Spot
by M De Simone 19 Sep '25

19 Sep '25

My AMI I sometimes doesn’t reject but if I turn the transfer motor armature a bit with my finger it takes off and all is good again until a couple records later. Does this mean I have a dead spot? And is there a way to correct this? Getting closer to working out the bugs. Thanks, Mauro Sent from my iPhone

wurlitzer OMT color motors
by Tony Miklos 19 Sep '25

Does a wurlitzer OMT use the animation motors with the worm gear on them? And how difficult are they to swap the worm gear from the old motor to the new? One more... who sells them? Not Victory Glass doesn't. -- Tony Miklos Tony's Jukebox Repair

I'm looking for a bulb socket from a Seeburg B,C,G, or W that illuminates the "100" mech cover insert. Anybody have one they are willing to part with? I found an online supplier but they have not responded to my email request Regards, Rick

Rockola 418 Blowing 28V Fuse
by mboessen＠ktis.net 16 Sep '25

Hi, All: I have not been on here in a long time. My bad back and old age have made me give up the jukes and pinballs. That said, one of my customers is a golf buddy, and he wouldn't take "no" for an answer. Last week he came with his grandsons and dropped off his Rockola 418 with a strange problem. It might play 10 records just fine. Then it will place a record on the turntable, set down the tone arm and blow the 28V supply fuse. It does it in that exact same place in the cycle every time it does it. It took me a while to remember that, several years ago it did this same thing. At that time, Ron, God rest his soul, advised me to check the 3 cam switches. One of them was, in fact intermittent, and I replaced all 3 with higher current rating switches. I have replaced the 28V supply 1.6A slo blo with a 2 amp circuit breaker to save money on fuses. Unplugging the AMP chassis does not clear the problem. If I unplug the Phono Power plug from the power supply, I can reset the breaker and it won't trip again, so I presume the short is in the phono wiring somewhere. I have it in fail mode right now. It would seem I have a short somewhere on this 28v line. I would like to just cave man troubleshoot it by unhooking wires until the short goes away, but to do this without a ton of work and agonizing twisting of my old spine, it would be nice to have a wiring diagram that shows the plugs and wire colors, so I can do that. The Victory Glass manual doesn't have a wiring diagram for it. Is any of you aware of a wiring diagram for this unit? Thanks in advance for any help. Best Mike

AMI Model I Selects 180 Degrees
by M De Simone 14 Sep '25

14 Sep '25

Please excuse all the questions but I’m having a hard time with this one. This is my most pressing issue. I recently rebuilt an AMI model I and when I select A1 it plays C19. It’s exactly opposite A1. Does this mean I put the basket or the pin wheel on wrong? Changing the pin pusher position does not help. Is there an easy fix or does it have to come apart again? Wanted to ask before I tear it down. Thanks, Mauro Sent from my iPhone

AMI I Selection Issues
by M De Simone 12 Sep '25

12 Sep '25

So I sorted out the previous 2 problems but now pulse is sent to the pulse receiver but the pin pusher or magazine doesn’t turn but the turntable starts. Following the schemagrams it seems like it could be the scan switches but they are hidden. How does one check and adjust them? I had the assembly out when the mech was on the bench and cleaned and adjusted them but I’m thinking something may have gone wrong. If any of the knowledgeable members here have any other thoughts, please share. Thank you, Mauro Sent from my iPhone

AMI model I120 Selectors Dead
by M De Simone 12 Sep '25

12 Sep '25

I’ve just put this jukebox back together, it hasn’t run since the 1980’s. All components have been rebuilt and/or checked out to make sure all switches were making and breaking. I turned it on for the first time and credit lights do not come on but in credit position buttons latch but pulse generator motor does not start. Where does the voltage come from for this motor as I measure 0 vac or dc for that matter. I believe it is an ac motor. I have the manuals but it just explains the sequence from “selection is made”. Anyway I’d like to see if I can get some voltage to this motor. Any suggestions welcome. Thanks, Mauro Sent from my iPhone
