Rockola Starlet Mech issue.
by Jukebox Repairman 25 Apr '25

25 Apr '25

Can someone who has a Rockola share a pic with me showing the orientation of the outer cam gear that operates the plunger on the gripper bow?I removed it to free up the trunnion and now I have it out of time. If I could see a straight on pic of the gear with gripper bow fully at rest and / or fully in play position that would be great. This happened to me once a long time ago and I don’t remember how I resolved it. Regards Rick

Another Wurlitzer 24 select question
by Tony Miklos 25 Apr '25

25 Apr '25

If I'm not mistaken, normally the jukes of this era, when the pin goes into the star wheel, the lift, or drop of the selector just barely goes far enough to align with the record trays. On this box, when the pin goes into the star wheel, the lift goes past the center of the tray, almost too far. After adjusting it, it is working well, but not engaging in the center of the tray. So it's working going up and down, but it's a bit confusing why this one goes so far when engaging into the star wheel. Any ideas? -- Tony Miklos Tony's Jukebox Repair

Wurlitzer 2900 Amplifier Issue
by M De Simone 25 Apr '25

25 Apr '25

I remember many questions about model 2900 on this forum and now I have a head scratcher, well for me anyway. I’m trying to figure out why relay RY5 located in the amplifier burns up. I have -29.5vdc across it (calls for -28v) and all the voltages around it seem to be very close as well. When I take an AC measurement across RY5 I get 15vac, not sure if that’s significant? It’s been recapped but C35 (3000@50v) is original and tests good with an esr meter. Any thoughts on what might be causing this relay to overheat? I’ve never worked in a model 2900.

Wurlitzer OMT Vinyl
by Jukebox Repairman 24 Apr '25

24 Apr '25

I started troubleshooting this machine awhile back but knee replacement surgery kept me out of the shop for a few weeks. I'm getting around better now and resumed working on this juke. I have determined it was stored in a very damp environment. To date I have replaced the K7 actuator, removed and freed up the frozen carrier motor, replaced one fuse in the amp. Upon power up I have a dead display, and the gripper motor loads, then unloads, the carousel rotates, stops and the gripper motor repeats the same process. This is my first OMT encounter other than replacing K7 actuators for customers which I have done a few of those. Looking for advice on where to go next with this one. Regards, Rick

Wurlitzer 24 Selection
by Tony Miklos 24 Apr '25

24 Apr '25

This particular problem is with the Peacock in my shop. When the mech clutch disengages and plays the record, sometimes it "ticks" from the pin not coming far enough away from the.. (I should have looked up the real part name) but it ticks as it passes the slots in the "clutch plate". It did have a problem with it disengaging too soon but I adjusted it and it now disengages when the turntable lift is at its peak. I had tried adjusting it a little each direction but still it sometimes ticks. -- Tony Miklos Tony's Jukebox Repair

Has anyone come up with an easy way to free up sticky record trays without disassembling the stack assembly? I'm dealing with a stubborn one that's been sitting idle for ten years Regards, Rick

Rowe Ami Tropicana mains hum background music
by Nigel Pugh 17 Apr '25

17 Apr '25

Hi All, I've got a perplexing issue here that am looking for some advice on. For 15 years I have successfully ran a background music add on to my Rowe Tropicana. I invented this and it has worked perfectly and kicked in when the jukebox finished scanning, re opened the mute relay to play line input until the user made a jukebox selection which would over ride it. The line in source was operated by switching in the signal at the volume pot. So essentially the power amp only is used to amplify the signal. Phase inverted as it's a Stereo Round jukebox. All that taken care of with isolation transformer in line. Anyhow, as I like to mess, I decided I wanted the input feed to go through the preamp to make use of the same tond controls and loudness contour of the jukebox. So I scrapped it all. I set up an RIAA inverter for the line in and wired the relay so both input feeds go to the preamp phono input. Now, upon testing. Jukebox audio from the cartridge is perfect. Line in audio has hum that increases with volume. If I bypass the relay and feed line in direct, through the RIAA inverter, it's perfect. Anyhow I narrowed the source of the hum down to the 28v ice cube relay that I use to switch between the signals. If I remove power to the relay by physically removing the 28v plus and minus wires, the hum disappears. But what I don't get is that when the relay is powered with the 28v, there is no hum (relat activated by the scan out switch on the mech). The hum appears when either of the plus or minus leads is connected and there is NO power to the relay. The relay is powered only when playing a record, hence it's not powered when the line in signal is present, but when there is no power, it hums. The unpowered relay coil is in no way connected to the source signal switching contacts. Is there anything I can do when the relay is not powered to, for want of a better word, break the circuit between it and it's power? Like adding a couple of diodes or something ? I don't get why it works when powered and initiates hum when unpowered. Any ideas please ? Thank you, Nigel, uk

Lack of oil/grease = sloppy Rowe gripper assy!
by John Robertson 15 Apr '25

15 Apr '25

Here's a first for my shop - a sloppy worn out gripper assembly where the Trunnion Pins #2-10792-01 are now a sloppy fit both in the mechanism base #6-08707-01 and in the Gripper Trunnion #3-07910-01. Check the parts manual for locations, other than the Trunnion Pins which aren't shown in the R-87 parts manual I used for getting the numbers. I assume now that these pins SHOULD BE OILED once in a while, like every ten years or so. I'll build this into my Rowe tips page and show the damage and how I plan to fix it if I can't find good replacement parts. Depends on how much the customer is willing to spend as well, this job is 3 to 4 hours at a guess. Needs boring, sleeves for both the base and Trunnion, and at least one new Trunnion Pin. Looking for a lube guide but so far nothing in my later Rowe manuals is turning up. Anyone have a factory copy they can send me? The manual says something like "Do not lube for ten years" - but then nothing about what is needed when that time is up! So, be warned when working on Rowe machines to get some oil on those Trunnion Pins - pull them out, oil, and put back. Synthetic grease may be better. Oil the motors too of course. There is a video on Youtube from abjukebox about lubing CD grippers but they recommend WD-40 which I can't abide with, that stuff leads to more seized machines then I care to think about...
