Wurlitzer 530 amplifier Low Volume
by M De Simone 23 Aug '25

23 Aug '25

Another amplifier issue! A W530 that has been recapped and any out of tolerance resistors replaced. Tubes all check good. I’m getting about 50% to 60% of gain it should have. I’ve run some tests and found the DC voltages are all low at the tube pins by about 20%. I’ve checked anything I could think of but no luck. Looking for advice as Im not well versed enough to understand where the voltages come from. Can anyone tell me what exactly the 4 section electrolytic capacitor C34 does? I’m suspecting it, as I replaced C35 (the other one) but C34 tested perfect so I left it in, just for now. Any help appreciated, Mauro Sent from my iPhone

780 Fuse blows
by ascott822＠aol.com 21 Aug '25

21 Aug '25

The amp was recapped two years ago and the box has been playing fine until recently. When there was no sound when recent selection was made then I checked the fuse. It was blown and continues to blow replacements. Sent from the all new AOL app for iOS

780 fuse blowing issue
by ascott822＠aol.com 20 Aug '25

20 Aug '25

Still trying to chase down the reason the amp fuse blows. I replaced the 5Z3 tube for the chance that it might have a short as was suggested. That wasn’t the cause. I removed all plugs into the amp and made selections and as I replaced one at a time as a process of elimination. The fuse only blows when the speaker is plugged in. Any help please.

AMI F80 Hum problem
by Jamie McElroy 19 Aug '25

19 Aug '25

Can anyone help me with this please. In the video is my G80 with a rebuilt amplifier. It plays beautifully. However, the other cartridge a when plugged into the amplifier makes a continuous humming noise. It will play fine but still hums. I cannot figure out why it continues to do this. Can you please help with this question. Thank you. IMG_4667.MOV <https://drive.google.com/file/d/1N1Wo3b6o0sPdx98nQ8GGDPYtfcbPlPp-/view?usp=…>

Wurlitzer 1100 not making selections - resolved
by wschaefer rileycopc.com 18 Aug '25

Hi Jim Dirksen and all, Thanks for the reply. I'll answer your questions to assist others who may have this issue in the future along with my successful fix. Yes, the selection light was lit. No action at all when a button was pressed. Pins were not moving. Mech motor was plugged in. I remembered that I had Harold Hagen's compilation of Wurlitzer tech tips so I took it out. In the Dr. Know It All Wurlitzer volume #1 reference book, page 67, there's an article titled "intermittent selections in Wurlitzer 1100". From the entire tech tip, here's what applied to my issue - "There are other switches in the selector coil circuit in the Coin Register Unit (grinder), so check them first: contacts 3 and 4 on the Timing Switch (activated by the cancel solenoid), and contacts 3 and 4 in the coin isolation relay. Make sure the contacts are clean and adjusted properly." Next, I went to my repair manual to see what a cancel solenoid looked like. From there, I saw the set of contacts actuated by the cancel solenoid. They appeared to be okay. Next I found what the coin isolation relay looked like and checked those related contacts. Well, I'll be..... one of the three sets of contacts was stuck together! I cut up a brown paper bag into a few little strips, sprayed the strips with contact cleaner, and cleaned all of the contacts in the coin register mechanism. I powered up the 1100 and voila, I was able to select tunes again. Grateful indeed.

Check the bulb. Do you hear a relay click or solenoid operate when you press a button? It's possible that selector pins are being selected, but the start micro switch is not starting the motor. Look at the rear of the pinbank to see if pins are moving. Be sure you didn't accidentally unplug the mech motor while poking around in there.

Scan/Service switch for early Rowe Ami
by Nigel Pugh 17 Aug '25

17 Aug '25

Hi all, The group looks like it's gone very quiet, or I'm having an email problem - I need to replace the scan/service switch on a JAO Diplomat and found new 3 way double pole switches made by CRL that seem to be common with Fender guitar amps. Some of the original jukebox ones were made at the time by CRL too. Has anyone ever used one or do you think they would work ? The only think I can think of is that the jukebox versions did not lock in for the "Scan" position, you have to hold them down. I imagine as these were guitar amp switches all the positions locked in, but that's no big deal. https://www.ebay.co.uk/itm/372877751680?_skw=crl+3+way+lever+switch&epid=11… Nigel, UK

Wurlitzer 1100 not making selections
by wschaefer rileycopc.com 14 Aug '25

14 Aug '25

Hi All, Last night I was giving my W1100 its semi-annual lubing and when I was done, I unfortunately discovered that it would no longer accept a selection. I've so far checked the two fuses (OK), the slug rejector (no jammed coins), and the coin register mechanism (no jammed coins). I was dropping in nickels & dimes pretty fast to build my credits to let it play for 20 minutes, hence me looking at the coin gear for a possible problem. I notice that when I drop a quarter, I can hear the 5 credits accumulate but when I then go to select a song, nothing further happens. I'm good with repairing most anything mechanical but since electricity is invisible, I'm slightly more impaired. [8^) Any tips are appreciated. Thanks, Bill Schaefer Castle Rock, CO

Wurlitzer 2900 selection issue
by Jukebox Repairman 09 Aug '25

09 Aug '25

Ok hoping the Wurlitzer experts can solve this one. This 2900 will not go to search / scan mode. It keeps loading the same record but even with all selection pins down. You can make a selection and it pops the correct pin but never goes into search mode. Just keeps playing same selection repeatedly. I’m not Wurlitzer savvy. Never have been My thought was a bad cube relay but the other issue is no manual to help troubleshoot Regards, Rick

Rock-Ola 1434 playing too fast!
by Tony Miklos 07 Aug '25

07 Aug '25

What in the world could cause this to spin the record faster than 45 rpm? It can't be the idler wheel since it's a single one. The motor is marked 115V 60 Cycle. There is no tape or anything on the motor shaft. While it was spinning I lightly put a file on the shaft to clean off anything that could have been put on it to speed it up. The inside of the "flywheel" is clean. There was a wire holding the one part of the motor upwards, the area where the rubber mount was failing and sagging worse than the others. They have been replaced and the motor is straight up and down. The motor shaft is in contact with the idler wheel properly, not near touching the larger diameter part of it. I don't get it. It's close to 48rpm. Funny how easy it is to hear a difference of 3 rpm, very easy! And yes I've checked it with a strobe disk and it shows that it's fast. If I can find the right kind of phone app to measure the motor's rpm, what should it's speed be, anyone know? -- Tony Miklos Tony's Jukebox Repair

AMI "Model B" Breaking 78s!
by Derek Thompson 06 Aug '25

06 Aug '25

This is a bad situation I can hardly believe it myself, I thought it was only a myth that jukeboxes actually broke discs. Had this machine about 13 years and had no problems once we took it apart and lubricated it etc. Within the last year or so there has been a gripper (transfer arm) jamming problem. If you switch the mains off when it jams you can turn the motor by hand and the record is returned to the rack and all continues as normal. Not however if there is another selection waiting to be selected. If you don't switch the mains off quickly enough, the rack starts to move even though the gripper has not yet returned the 78 to the rack! Hence breaking everything in its path. I assumed this was a lubrication problem, however recently the same thing happened again after lubrication, I lost 15 of the 20 discs this time. I assume it is something more, why is the rack starting to move before the record has been returned? You can avoid this potentially happening by only selecting one record at a time, so the rack will not move if there's a problem, but it needs sorting clearly. It can go a long while before jamming, other times it can jam repeatedly, it's random. Am pleased to see this list still exists, it's many years since I used it. Thank You. D.
