It's only needed whenyou use wallboxes. I had a problem with mine long ago where the coil openedon the selection timing relay. This caused the credit solenoid to stay activatedand it did make a very loud buzzing noise. So as you know, the first step is tosee what's buzzing and fix that, so the machine can be put in a known point inthe play cycle. The fact that the buzzing starts as soon as the machine is turnedon indicates it's coming from an electro-mechanical rather than audio source.

Seeburg M100A Buzzing

This is a bummer juke to work on. someone else has been it a few years ago. I have discovered: 2050 tube missing, reject button , 2 wires pulled out of plug and each wire attached to the terminals of the visible fuse on the bottom of the wsr, Large plug that was supposed to go to the credit unit was plugged into 6sl7 socket on the amp. 6sl7 tube is now missing. Mech sits and spins, wont move or reject. Jim

Seeburg M100A Problem
by Jim McClave 30 Mar '24

30 Mar '24

Still working on the loud buzzing noise problem on the A. Cant really tell if the noise is coming out of the speaker or somewhere else. Is it ok to temporarily disconnect the speaker plug without damaging anything else? I know B+ goes thru the field coil. Jim

Hi all, I’m trying to hook up a 5207 wall box. We have a 2304 Wurlitzer with a stepper. When I tried to hood it up the wall box started to smoke (just for a second) so I unplugged it! Any help would be greatly appreciated, thanks Sent from my iPad

Seeburg B selection issue.
by Jukebox Repairman 29 Mar '24

29 Mar '24

I just serviced a pinbank for this model b. However selections A,C,E,G,J numbers 5,7,9 are not working. The individual pin coils were clean with no visual evidence of burn. The strain relief on the jones plug was missing and when I removed the cover found one loose wire. I solder it back on thinking this was my problem but still these selections do not pull pins. Mech does scan if pin is moved manually. I bypassed the selection receiver mating the jones plugs but same issue. Regards Rick

I’m currently working on this amp from an S100 There is a semiconductor that is burned. Parts list shows it as a silicon stabistor. I know it’s a special kind of diode but where can I get it and does it have a certain value? The parts list shows it as CR5107 Regards Rick

Re: AMI JBM200 Tropicana question

Hi Dean, You may find the issue is still the #3 switch, because even though it works ok, the transfer time between the contacts may be too long. For the search unit removal. Remove the power, then the comb edge connector from the search unit. Now remove the 3 large bolts in each corner of the search unit. Leave the last one in and steady it as you pull forwards. It will come off easily. Now you will see the stopping switch assembly. Only one of the switches on here is the stopping switch. Remove the circlip and pull forward. It will come off. Check the switches on the bench and check their connectivity on the wiper circuit on the rear. Clean the wiper tracks and clean the wiper contacts (these are still in the jukebox). Check dry joints where the wires from the stop switch is attached to the wiper track. When done set the carousel so that U0 (I think it's U0 but will clarify later) is at the top. Now slide the stopping switch assembly back on and line up the words 200 to the 3 o'clock position where there is a bit of a ledge in the mounting bracket. Also make sure you wind the record playing annunciator round to show U0 also). Re fit search unit and bolt up. Don't mess with anything on that unit as it has nothing to do with your problem. Connect the comb edge connector and select a record. Try all selections like A1,B2,C3,D4 so you have covered all letters and numbers. If the search unit spins forever on a certain letter or number then it's a poor connection on that comb contact. Hope that helps to get you going , Nigel, uk > > On 12 Mar 2024 at 07:52, Dean Carriveau via Jukebox-list <jukebox-list(a)lists.netlojix.com> wrote: > > > Nygel, Tony, and John, > > Update, > I've checked the CS3 Micro-switch as I manually turned the cam with an Allen wrench. Both the NC and NO terminals showed the internal contacts top open and close properly with my ohm meter at it's lowest setting. Very little or no resistance. The control relay "R" operates and released correctly when I turn the cam manually to start the transfer motor and it will load and play a record, then after playing will return the record to the carousel. so I believe the "R" control relay winding is okay. I would like to check the stopping micro-switch but don't have easy access to it with the search unit still in the machine. I'm a little apprehensive about removing the search unit to bench test the micro-switch and then throwing sequencing out of adjustment.

Seeburg A problems
by Jim McClave 19 Mar '24

19 Mar '24

Initial first look at a friends Seeburg M100A : Fairly loud buzzzing noise as soon as power is applied. Mechanism is stuck , wont move, even by turning the hub with power off. With power on the hub turns, but wont trip or do anything. I believe the buzzing is coming thru the speaker. Clutch problems?

I'm trying to join the facebook jukebox market place and I keep getting turned down. On the "application" I wrote that I repair jukeboxes and would like to join to look for parts. A week or so later I get an email saying my application was rejected or something like that. What the heck? Do you need the secret password and handshake? Tony
