Seeburg M100A Pickering Cartridge
by Andrew Burkhart 26 May '25

26 May '25

I’ve read about the M100A Pickering cartridge, it needing to be rebuilt, and I have questions. Will all original carts need to be rebuilt at some point? What fails in the cart that causes it to need rebuilding? After a proper rebuild (say from Wes-Tech Services) has anybody had to have it rebuilt again? How long will it last (very roughly) after a rebuild? Besides Wes-Tech, who else rebuilds these? Every now and then there’s someone on eBay selling some sort of goop and instructions to rebuild this. Anybody here go this route? How well did it work? My cartridge is still working and I believe it has not been rebuilt since it has the original black rivet. I may have read about some of this in the Jukebox-list archives before they were lost. Hopefully, the responses will help add this info back to the group. Andrew

Seeburg KD amplifier bench test
by M De Simone 25 May '25

25 May '25

Can I bench test a Seeburg KD amplifier? I’ve never attempted it before. I have a jig setup for testing other Seeburg amps, it’s plug and play, I have the whole back door. It seems that if I just attach speakers, an input and plug it in it should be the same but thought I’d check here to see if my thoughts are correct. Please let me know if any of the fine members here have done it. Thanks, Mauro Sent from my iPhone

Q160 pickup past A1
by jukeboxbob＠juno.com 23 May '25

23 May '25

HI Yes I have owned the jukebox for years. I recently had the mech out of the machine because the record transfer arm was seized on it's pivot point. I gave the mech a good lube job. It sat not used for a couple of years. I guess I could have disturbed the contact block. I'll check it out. I have the service manual. Thanks Bob

Rowe CD100 Mech Control Computer

Hello All, Tried to search archives but it refuses to load. I'm sure I'm not the first person to plug in a proplayer back wards but I bet I'm the first person who sure as heck knows better and did it anyway. Back before I retired when an employee did it I had plenty spare parts around, swapped it out and had another employee fix it. Things are different now and I did it to TWO computers before I realized what I had done, and this is my sister's jukebox. I'm fresh out of spares and am hoping someone knows exactly which part I let the smoke out of so I can get her back up and running quickly. TIA, Karl, Formerly of Columbus Coin-Op Shop

Seeburg M100A Pinbank Issues
by aburkhart＠unilect.com 22 May '25

22 May '25

After having much success with getting a couple of Rockola machines operational, I am now getting into the Seeburg world! I have a Seeburg M100A that was converted to 45 play with the CalCoin kit, and which I intend to convert back to 78. I have 2 manuals for the machine, one from Victory Glass (the nicer manual) and the other from Jukebox Arcade (has some extra info than the VG one). My machine has two issues as I can tell: 1. When making any selection, the selected pin is not moving into the play position. I can manually trip a pin and the machine will go to that selection and play. 2. After playing a selection, the record is put back in the rack but the pin is not canceled, and the mech will search and go to the same selection to play. I manually cancel the pin and the mech will stop, as it should. The credit system is adding credits with coins as it should, and removing credits when a selection is made. And the amp is working well. I do not have an analog VOM yet, but one is coming soon, and I believe I need that to help diagnose this issue from what I have read on various forums. I am seeking guidance for the two issues presented above, and would like to know if the subsequent models B and/or C are in any way similar to the Model A as to the pinbank operation when searching for info on the web. I have also ordered Ron Rich's mech guide, although, it may not cover my specific model - I am hoping there may be enough info to help at some point. I measured the various solenoid resistances and they are within range, and free moving. What should I look at first after I get the analog VOM? TIA! Andrew

Wurlitzer 546B amp
by Tony Miklos 16 May '25

16 May '25

I have a strange one here. A wurlitzer 2910 with a 546B amp (what is a "B" mean?) The amp looks near perfect with a square wave on a scope, but in the juke with that weird speaker set up, it's missing something. First I found that when the amp is set to Mono, the volume goes way down. Changing the bass treble and balance seem to do not much at all. Swapping left and right phone input plugs, showed that one channel on the cartridge was real weak. I put a new cartridge in it and although it sounds a lot better, it really acts strangely when adjusting the bass and treble. depending on the other channels settings, if I lower the bass on the other channel, it gets way more bass, I mean a lot more bass! Moving those switches just makes it do some really weird stuff. No rhyme or reason to it. I did clean them and on the bench, everything looked and acted fine. I don't think there is any crossover except a cap on the one midrange/tweeter that I need to replace. The way the treble is sounding, that cap may be shorted. Now that my back is feeling a little better I'll replace it. From the parts manual I think it's a 22uF bi-polar. What a weird setup. Two different types of 12" speakers and one mid-high range. There is room and even slots cut for another mid-high range but no mounting holes or studs. -- Tony Miklos Tony's Jukebox Repair

Rock-Ola 1448 makes a group of wrong selections
by M De Simone 14 May '25

14 May '25

Need help! I am working on a 1448 and during test running found that selecting 61 through 80 plays 101 through 120. Can anyone shed some light on this? It’s being picked up on Friday and I have to have it sorted out by then. Many thanks, Mauro Sent from my iPhone

Rock-Ola 1446 for sale
by Tony Miklos 09 May '25

09 May '25

I have a Rock-Ola 1446 with a deadbeat owner. I've had it stored for almost 10 years and would like to get it out of my way. It was/will be working, the cabinet is finished in oak veneer and the inside painted. The top side of the machine mech, shroud, side panels, mirrors are all done. and everything works. The front door is not done at all, it's in worn condition but I think the grill is very nice. Unfortunately I can't find the pics right now and it will be a bear to pull out and unwrap. So until I find the old pics (may have to make my old PC work) I'd unwrap only if someone is very interested and will come to look at it. I am in Newport, TN. I was asking for $2,000 for the work completed. Is that price inline for a box fitting my description? I now know better to get a down payment for big jobs. -- Tony Miklos Tony's Jukebox Repair
