R-85 keyboard and display
by Paul Howlett 18 Jan '26

18 Jan '26

I changed a record, now the display only shows a couple of digits and the keyboard only the popular button works. The rest of the mechanism works fine. Paul Howlett Pinball Paul's 703-361-0420

LPAD for side speakers - Rowe Ami
by Nigel Pugh 11 Jan '26

11 Jan '26

Hi all, For more years than I can recall, my JBM Tropicana has been across the corner of the room. Due to a room redesign it now can only go in one place, along a straight wall, one side speaker about 8 inches from the wall, and the other open to the complete room. The rub is the one open to the complete room now faces the seating area and the direct sound from that reaches your ears before the front facing bass does. So I have midrange overload in my ear until I walk in front of the machine and then it sounds fantastic. So I had an idea to use the speaker transformer taps to reduce both sides speaker outputs. This has absolutely fixed the issue, which I can only describe as a Rowe Ami design feature probably to show off stereo in its early days but a bit annoying. I remember having to do this on someone's Continental 2 30 odd years ago. Anyhow this is my ask here. The outpost difference between the 2 speaker taps is too large. It goes from lots of side speaker output to not that much. I would like to vary it. Could I use 2 LPADs connected to each side speaker, set them on high output tags and use the pots to lower the output to the sides ? This way I could get the precise output I want and also compensate for the fact that the other side speaker is smashing the sound up the wall which is reflecting it back more than the speaker in the open room. Hope that makes sense - it's a question about LPADs. Are they ok with tube amps. The spec is 8ohm each side speaker. Thanks, Regards Nigel

Missing pages for Wurlitzer KIT 102 - adding Cobra Tone Arm to 1015 or 1080
by John Robertson 02 Jan '26

02 Jan '26

Hi Gang, Please check if you have any documentation on the KIT 102 - specifically Sketches 1, 2, and 4, as well as an overall schematic. This is what I have currently - thanks to Matt Potter: https://www.flippers.com/pdfs/Wurlitzer_USA/Kit-102_Cobra_Install_on_1015-1… What I have is missing those pages and while it explains how the kit is installed and set up those pages would aid in troubleshooting. The kit's pre-amp does NOT match the schematics for the 1100 Cobra pre-amp... Thanks!

Fast Autoranging DMM
by Tony Miklos 02 Jan '26

02 Jan '26

Does anyone know/use a really fast autoranging meter? I'm looking at this one to try. (I didn't see a price yet) I think it takes .8 seconds to read but I got that spec somewhere else. https://www.eevblog.com/forum/testgear/fastest-dmm-ohm-autoranging-suggesti… I'm so used to my ancient Beckman 310 being so quick, but it isn't auto-ranging, so that of course makes it slow if I have to turn the dial. -- Tony Miklos Tony's Jukebox Repair

W1015 sound system Volume box
by M De Simone 31 Dec '25

31 Dec '25

Seasons Greetings! I’m working on a Wurlitzer model 503 amplifier and volume control box (all original). This set up also has a Jacobs preamp installed. I’m having issues with the volume control box (I believe), I’m using an iPod for a signal, when I plug it directly into the amplifier it sounds great, when I use it to test the preamp there is a slight increase in signal from the input to the output, so I’m assuming these components are all good. When I connect the volume box into the circuit I lose almost all the signal, everything is newly replaced in the control box except for the coils. I’m suspecting L2 but have never had to replace one and not sure how to test it? From the schematic I’m guessing one of the tabs on the coil is just an isolated binding terminal, I suppose what I’m asking is how to test and find the issue and if need be where would I source a modern replacement? Thanks for any help, Mauro Sent from my iPhone

Seeburg Turntable bushings 100R
by Jukebox Repairman 29 Dec '25

29 Dec '25

In 25 years of repair I’ve never had the need to change a set of turntable bushings which obviously requires turn table removal. If any members here have performed this mech surgery before are there any tips you’d care to share to make my job a bit easier? I’m guessing that after 70 plus years the turntable has probably bonded itself to the bearing(s) Appreciate any tips. Regards Rick Jukebox Repairman

Continuous scan Seeburg DS 100
by dvachon3＠teksavvy.com 28 Dec '25

28 Dec '25

Happy Holidays to all. I have a DS 100 that continuously scans. It will pick up selected records but won't stop scanning after the last record plays. The subtract solenoid does not move when the mech scans to the right. I checked the subtract switch on the back of the mechanism it has continuity even with the blades separated. The subtract solenoid in the selection receiver doesn't seem to be stuck. Is there something else that I should be looking at? Thank you, Doug

Rowe/AMI Trunnion Pin
by Tony Miklos 20 Dec '25

20 Dec '25

Hi John if you are reading this. Not too too long ago you posted about a trunnion pin wearing a hole in I believe a shaft. I was looking at an R-91 manual and happened to see a trunnion pin listed and it's relative location, but the diagram doesn't show it. Is it shown in older manuals? Thanks, Tony -- Tony Miklos Tony's Jukebox Repair
