What are you looking for, that is a good question Eugen!
I think first have a good look at the two coils that have been tampered with. What I was calling the drive solenoid is in fact called the index solenoid (yes my pdf is that bad) and there are two further drive solenoids which set the index position. I cannot understand how that indexing works for all selections other than the two tampered coils - but I think they have to be your initial focus.

Norman, yeah, taking it apart now. Interesting thing is that G1 through G5 started to work fine... something must be sticking in that area.

B1-B5 coil is installed upside down. At least I know why B4 is not triggering LOL

Wow, everything is working after I flipped the coil. B1-B5 are firing pins properly. G1-G5 - I just cleaned around them, double-checked everything, cleaned the solenoids - but those 5 are selecting properly now too. Now will start adding missing pieces to the selector keyboard - play counter, Select light harness, and button cancel microswitch (when it will arrive). photos.app.goo.gl/KF2U5MHf5tubwSwD9 |

Well I think we would have scratched our heads for a long time before we would have come up with that as something to check! Glad it's working!

Updating my to-do list:
- completely rebuilt the amplifier
- took apart record carousel, cleaned and and put it back together
- rebuilt playrak with new coils instead of completely burned out ones (some genius bypassed the previously failed breaker), installed new fuse/fuse holder instead of failed breaker
- cleaned all contacts in selector keyboard; repaired bad soldering in the selector;
- cleaned and recapped selector junction box
- cleaned/oiled/lubed the mechanism
- rebuilt/cleaned/oiled record player - new motor mounts, new belts, new needle, adjusted needle pressure (was maxed out previously)
- cleaned coin acceptor - looks like someone pulled some parts related to accepting 10-cent coils, as it only accepts quarters, and rejects all dimes.
- replaced crossover capacitors; bought new tweeter instead of a failed one (open voice coil); repaired mid speaker cone
- bought replacement coin door
- completely rebuilt mechanical part of playrak - now it adds and subtracts credits properly
- repaired selector (with flipped coil)
- tested all 20 coils (tried close to 50 selections already)
- installed play counter, built and added Select light harness, installed new top diffuser paper over keyboard instead of one that got jammed behind buttons
To do:
- install release buttons microswitch on selector keyboard - in the mail
- install new tweeter and reinstall repaired mid speaker into the cabinet
- replace record guide plate (mine has a few cracks, need to buy a new one)
- replace front glass if I ever find an affordable one
- still need to reinstall the caster that fell off
- repair coin door if possible (particle board part is water damaged)
- put the whole thing back together in the cabinet

I am trying to maintain some kind of pace and finally started putting this jukebox together. I can say that even with two people it was pretty hard to reinstall the dome onto the cabinet. New tweeter was much better sounding than the remaining one in the cabinet, so replaced the 2nd one too - I am sure that one was replaced some time ago, there were no markings on the tweeter (compared to the one that was completely open and had all proper part numbers on the magnet). I installed new release button microswitch, had another headscratcher why previous owner completely removed it and all associated wiring; put keyboard together and reinstalled into the cabinet. Playrak and coin acceptor are in the cabinet now too. The room has so much more space now! Will reinstall the amplifier, and will wait for help over the weekend to put the mechanism into the cabinet. Repaired coin door mostly, at least it fits into the cabinet now - next time I will just get piece of plywood and cut a new door rather than playing with this pressed wood stuff. Spent a lot of time cutting and installing two caster bases, caster sockets and new casters - previous owner somehow decided to throw those out and install completely wrong casters (which fell off eventually). Also built a decent aluminum frame around the bottom of the cabinet - bottom one inch of each side was very damaged. Replacement record guide plate, plastic record indicator box and top decal are in the mail... maybe one day I will find an affordable front glass, or will just buy a repro from Victory Glass... So almost done, hopefully will have three playing jukeboxes for Christmas. photos.app.goo.gl/3fxkUAZGVF82yp9g7 |

Hi Eugen,
L@@kin' good !
Just curious-- is there an ID tag on the rear, outside of that cabinet-- If so, can you shoot a photo of it ? Ron Rich

Hi Ron, this one? photos.app.goo.gl/TKKxyCbkJ7K13XGu7This 3010 only has one tag, but my 1900 has two tags - I guess, one for the Canadian-built cabinet, and the other for the actual jukebox mech. |

Hi Eugen,
Yes-- that's what I was looking for-- and the reason was-- that cabinet looks like a 2900 series cabinet, rather then a 3000 series cabinet. The mechanisms, and all electrical parts would have been the same-- perhaps they had left-over 2900 cabinets, and decided to build the small phono in that cabinet ? Ron Rich

Hi Ron, the guts of 2900 and 3000/3010 are almost the same. The service manual for 3000/3010 is 2900 manual plus a smaller "appendix" to describe what is "new" in 3000 series, but 80% of the manual is original 2900 one. I believe, 2900 and 3000 hold the same number of records; same with smaller 50-record 2910 and 3010. Interesting that 2900 was only made in 1965, whereas 3000 was made in 1965-1966. 3000 series is also much heavier than 2900 series according to Jukebox History website. I can confirm that the cabinet is very heavy, it has double sides, since side panels can be changed.

Hi Eugen,
I think the information you saw is erroneous-- The info I have says the 3000 was a 1966 model-- the 3100, a 1967 model--3200's 1968-- Ron Rich

Eugen,
All major manufactures did so,just like the auto industry-- and most did at least two a year-- Ron Rich

Just to close off this topic. This ended up to be the best sounding jukebox that I have lol. Here is a photo: photos.app.goo.gl/xQemdCCiFUTomWTa9 It is sitting against the wall and with 1900 to its left, so I have no easy access to volume control or cancel button. Hence, I bought a remote volume kit, which I still need to install. I am starting restoration of Wurlitzer 5207 wallbox for the 1900, so will post a separate thread for it. |
