Thanks for this explanation! The readout arm on our Rockola 440 will not stop on a selected "B" side pin ("A" side pins work without issue). Upon inspection, it appears the wires that connected to the B-side coil within the readout assembly have become dislodged and are no longer making good contact. What is the best way to re-attach the two wires to the coil? Thanks again for your help.
the read out arm is easily removed......take off the nut on the end of the bolt that secures the read out arm to the main shaft. Remove the bolt and pry off the arm. Check continuity of both coils. Should be around 30-50 ohms each. Then bend the wipers slightly to ensure good contact with the read out circuit board before reattaching arm. If still no non hit side selections, go underneath and watch the A/B switch as you scan the magazine. Be sure it is going up and down. If not you need to service the alternating dawg underneath. Also reseat the molex connector that goes from the A/B switch assembly over to the bronze control box and the round pin bank.
William, PLEASE HELP ME!!! I HAVE read and reread the manual but have never worked on anything like this. I have a Rockola 440 that worked perfectly for 2 years. Then after the reject button /skipping a song with no backup selected it has not worked since. Operation function spins the turntable. Scan function does not flip the magazine. The write in functionality works. As soon as the arm makes the selection correctly. The read out arm never moves. It is frozen as is the magazine. I have no idea what to do but would love to know if there is something stupid to fix it that I have no idea about. 1. I have no idea what I am doing but kinda have to assume it’s wobble or magazine motor relay problems ¯\_(ツ)_/¯ Thanks so much. HELPPPPP
Aaaahhh. I don't have a 440 here or a 440 manual. What I would do is lift the lid and manually flick a pin up on the right round pin bank to the far right. That should do the work of the wobble plate solenoid and should close the wobble plate switch. If your read out arm and magazine then start, it is possible your wobble plate solenoid failed. If nothing happens when you flick (select) this pin manually, then you may have blown the 1.6 amp mech fuse. This as I recall is on the front of the power supply which I believe is on the bottom left of the jukebox cabinet. Check this fuse for continuity and replace if it reads open. If this is not helpful, then, yes, it get stickier........you will need to check the bronze control box under the mech and remove it. There is a magazine relay in there as I recall that could have gone bad. Check its continuity
William, I have a Rockola 441 with what seems like an easy problem: There are a few selections that the sweeper cannot find; it just continues to go round and round. Tried cleaning everything I could get to with no luck so far. Everything else works fine. Any help would be appreciated.
You picked the one model Rockola that I have avoided because of the tube amp. So I have ZERO experience with a 441. If it is like the 437-440, then the likely suspects here are the keyboard and the write in (K3) and stop (K4) relays that are on the power supply on the bottom of the box, on the left. If you are able to access the power supply and clean the relay contacts on both these relays, do it. If no luck, then go to the keyboard with the jukebox powered OFF and exercise every letter and number button by pressing it in fifteen times since dirty keyboard contacts interrupt the signal needed in the selection process. In fact, the keyboard is the Achille's heel of these earlier Rockolas and sometimes you have to hardwire all the letter and number buttons since they are in series and if just one letter or number switch is not making a good contact, the selection process will be interrupted. If nothing good happens, I would join the Rockola Jukebox Club group on FB and post your problem so others with more experience with 441s can give their thoughts.
Morning, I have a 448. The selector arm turn table and record carriage keep turning when power is turned on. I can select anything in the 200 range and it plays. If I select anything in the 100s it seems to accept the numbers but then does not select the record. Is there a chance that the two issues are related? From what I’m understanding, because the numbers seem to be selecting and latching but the motor just spins, I’m looking for a loose wire or bad connection. Would this is also explain why the motor just keeps spinning even after it plays something from the 200s? Thanks for posting your video and any direction you can offer
First thing to do is to go to the right side of the round pin drum and be sure EVERY pin is put back in the unselected position. Most likely one pin is in the selected position and that tells the magazine to keep searching for it. If you find this condition and correct it, the magazine should stop where it is supposed to stop in the home position (the gap). Then lift the lid and select 124 which should be a pin on top of your round pin bank. See if the write in arm stops at this pin location, see if the current limiting bulb flashes, and see if the write in hammer coil tries to hammer the pin or not. Then report back. You may have to join the Rockola Jukebox Club group on FB and post videos of your problem so I and others can try to help. Write in problems can be complex.
I would not use sandpaper or abrasives. usually a soft cloth soaked with WD40 wiped over the PCBs a couple times is fine. Follow it up with a spray of CRC contact cleaner and rotate the arm a couple times.
Thanks for the videos. Im currently trying to get my 464 working. The 3rd number locks and the write in motor starts and searches but never triggers a pin. Any suggestions..
The three most common problems that cause this: Dirty write in circuit board and wipers (so clean them). Faulty K4 (stop relay) circuitry (reseat this relay, check it's continuity.....may be necessary to remove the cover and clean it's contacts). And a loose wire going from the selector drum to the selection control box (so reseat ALL the molex connectors in this pathway and examine for loose wires). It may be necessary to go into the power supply and replace the 100 uf cap in the K4 circuit. Sequence 6 in the manual is where you should concentrate. Most of these issues are mentioned in the next to last video, which unfortunately was not good technically with the narrow field of vision.
