AMI E120 - Selector - I'm struggling
by Jamie McElroy 13 Dec '23

13 Dec '23

Hello, I have an AMI E120 jukebox. My junction box is putting out approximately 38 volts. I have credits on my credit unit, the credit unit light comes on. However, none of my selection buttons work. I cannot figure out what the problem is. Does anyone have any idea or help they can offer. I'm struggling for a couple weeks with this. Thank you for your help. Jamie

Wurlitzer Lyric Flexible Drive
by Peter Johnson 13 Dec '23

13 Dec '23

Hope someone can help with this question. I have recently rebuilt a Wurlitzer Lyric for a friend who dismantled it 30 years ago? The flexible drive from the number selection unit is giving me problems, it tends to twist as it drives and stops/stalls turning the toothed selection wheel. I have soaked the outer sheath of the drive with a penetrating oil but doesn't make any difference. My next step is to remove it from the keyboard and see if I can examine it more closely to see what the problem is. Any help or advice would be greatly appreciated. Thankyou. Peter Johnson.

Another APFEA1 Question
by Jukebox Repairman 13 Dec '23

13 Dec '23

Machine has credit Make selection but the Add solenoid on play control does not fully engage to start the mech scanning. It does start manually via the service switch. I visually observed the solenoid while a helper made a selection and I could see the solenoid plunger move slightly but not enough to activate motor control switch It acts like it’s only receiving a short pulse from the button selector. Thoughts?? Regards Rick

Scope for Wurlitzer Amplifiers?
by Shankar Singh 12 Dec '23

12 Dec '23

Hello, Is this a suitable scope to troubleshoot Wurlitzer amplifiers? Would a signal injector be required as well? https://www.amazon.com/Oscilloscope-Persistence-Measurement-Bandwidth-Gener… I have only done a few basic repairs and servicing, so am still a novice. If it can be helpful, would appreciate early response; there is time constraint to ask a friend to assist with the purchase. Many thanks 🙏 SHANKAR SINGH

MRA4-L6 Schematic
by Tony Miklos 12 Dec '23

12 Dec '23

I've looked and looked for a schematic for an MRA4. What model did they come in? I think someone told me that they came in hideaway units. I did somehow find a parts list for an MRA4, and it's very close to an MRA5, I'd just like to have the proper schematic. I don't mind buying a manual, but I don't know which one. The particular one I'm working on evidently fried the power supply choke and to make up for it, they made C1 out of 3 caps to get close to 300uF. Tony

WurliTzer 2900 Top Tunes Installation.
by Shankar Singh 30 Nov '23

30 Nov '23

Hello there! Hope you are all doing well. I believe I now have all the components for the Top Tunes feature installation - Control Unit, Golden Bar & switch assy and the Latch Pin Actuator Arc Assy. I would re-cap and test the other components in the Control Unit. Would appreciate some advice for the following: Tips for servicing the arc assy. Can something be turned by hand to test the unit?Or should I plug up and test the arc unit before installing it onto the selector pin-bank unit? Tips for installing the components. Any instructions available that can be shared? The T.T Control Unit has a 12-pin socket, which appears to be for the Golden Bar Switch. It also has a 4-pin socket that looks like one for the Slug Rejector plug. Is the Slug Rejector now plugged in here and a jumper required for the Slug Rejector socket at the Coin Mech/Playrack? Many thanks! SHANKAR SINGH

AMI E120 Gripper Arm Return
by Jamie McElroy 28 Nov '23

28 Nov '23

Hell all, can anyone help me with this problem please. When a even selection of a record is made the gripper arm returns the record to the proper slot it was selected from. However, when an odd selection is made and played, the gripper returns the record into the next slot on the record rack. This does not happen every time but 85% of the time it will when an odd selection is made. Any thoughts on this please. I'm going a bit crazy with it. Thank you for your help. Jamie

My memory of the component name isfailing me, but if the lever switch on the carriage, when it strikes the selectionlever for an odd numbered record, is in the wrong position it will stop thecarriage too early or too late to put the carriage in the right position toremove and replace the record. The only other thing that would cause itto be returned to the wrong rack position would be if the carriage movedbetween the time the record is removed and replaced, and since you didn'tmention that happening (and I can't envision a condition that would causethat) I'm assuming it's an alignment issue. > > > > > > > > _______________________________________________ > > Jukebox-list mailing list -- jukebox-list(a)lists.netlojix.com > > To unsubscribe send an email to jukebox-list-leave(a)lists.netlojix.com > > %(web_page_url)slistinfo%(cgiext)s/%(_internal_name)s > > Searchable Archives: http://jukebox.markmail.org/ >

Seeburg APFEA1 Mech Issue
by Jukebox Repairman 28 Nov '23

28 Nov '23

I currently have this machine in the shop and troubleshooting an issue. With credit on the machine, a selection is made but the add solenoid in the control center does not engage fully to open the motor control switch. With the power removed, the plunger moves freely manually with no drag or bind. If I manually scan the mech via the service switch, the solenoid engages and the mech goes fully into scan mode. It acts like the solenoid is only receiving a short pulse. Does this sound like a faulty service switch or contacts in the Electrical Selector? Regards, Rick
