Yes I got it that you got it working, I was just trying to add a little more info, when working with nylon anyway. Some plastics shrink with heat and age, which could be why yours cracked (age). Anyway, good job on the fix! Also, some types of plastic can swell if oiled.

Rockola Nostalgia 1000 power switch replacement
by bpoldstyle＠yahoo.com 29 Aug '25

29 Aug '25

Hi, I'll be visiting a friend who has an issue with his Rockola Nostalgia cd jukebox. He claims that the power switch is a little "flaky". Sometimes he has to rock it back and forth numerous times to get it to turn on the jukebox. From what I've seen online it appears that the switch is built into the power supply....is that correct? Would I be able to bypass that switch and wire in a simple single-pole toggle switch for him? (online it looks like there are more than just two wires connected to the switch). Thank you, Bruce

Seeburg cartridge holder
by Nigel Pugh 26 Aug '25

26 Aug '25

Hi all, For later stereo Seeburg cartridge with the yellow / green / purple shoe type styli, I am sure a few years back someone was selling the replacement holder assembly – the clip part where the cartridge pins sit in the tonearm, and the flat locator clips in the tonearm. I need to replace the one I have. I’m pretty certain it was Ron Rich that mentioned the new replacement part a good few years back. The older ones can get loose and troublesome even with the pin sleeves tight. Does anyone know it ? Thanks Nigel, UK

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

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
