Nsm City 2 - the journey and rebirth
Olper:
Joecap, you are close to a working machine. The most common thing is that the old lubricants in the motors and other shafts get sticky.
Watch this:
It could be that WD40 will losen up the old lubricants so that your motor starts spinning. If the "record wheel" is stuck, it will not move even if the motor itself does spin. If the rubber wheel is just a little bit stiff, then the record wheel's rubber will slip and the music will be in slow motion. I wrestled with this. Had to clean up the rubber many times, had to clean up the tip of the axle that spins the wheel, and had to WD40 the rubber wheel's shaft.
WD40 may help you get the things moving, but ultimate fix would be to disassemble, clean up, and then relubricate with appropriate lubricants.
I recommend you try to make things work the easy way first. Then when you know that everything works at some level, only then should you start really getting into them. This way if you accidentally break something while trying to make it perfect, you will know that the issue is new and has something to do with what you have just done.
Best of luck!
I also have a NSM City II, and am working on it. I got it spinning records and hear the sound. It's cracking and popping. I bet the amp need electrolytes. Maybe some signal wires are bad too.
My device will not pick records itself. The lever is broken - snapped from the middle. I have new one coming and hope it will be good.
Also the front door is broken - the lower frame has cracked off. It needs screws and glue, and some black filler mass to make it new again. Also I'm missing the front window..
I've been buying records like crazy during the last 2 weeks :D I think I have more than 100 coming my way. Now i MUST fix this juke :P
Would love to hear from Legtod2, did you get the amp working? It's been more than a year.. I hope you haven't abandoned your project, as you were so close to have it fully operational :/
Olper:
Yo Legtod!
I'm gonna redo all my capacitors too. I wen't through them and noticed that some of the aluminum cased capacitors are not indeed aluminum electrolytics. The difference is that aluminum electrolytics are polarized, while the other ones can handle AC.
Maybe you replaced some of the AC capacitors with aluminum electrolytics?
I got good pics of all original caps. If you help, give me a shout!

Victory Glass sells some NSM service manuals. I see they have the model 240 and model ESII manuals/schematics.
And yes indeed NSM was bought by Rowe-Ami (AMI Entertainment) a couple of years ago. Some NSM information is here:

Hi Everyone - I just noticed this thread and may be able to contribute as I acquired a NSM City 2 last year and managed to repair most of the problems that it had, along with improving with a few add-ons:
- Carriage base was stuck to the left side of the rail with a non-stop clicking sound
> Solved by a combination of cleaning the contacts in the base and leveling the rail properly (supporting springs not arranged properly)
- Only left speakers were working
> Blown transistor on the carriage electronic board
- "Low quality" sound
> Solved with a new needle
- Added Bluetooth receiver
> built a 5-pin DIN adapter to combine Bluetooth audio feed + Regular Carriage base feed on the same plug (but different channels) - working beautifully switching from one feed to the other via a switch (installed in place of coin recall button)
- Added Multi-Color LED's (cool effect)
Last problem not fixed so far is the vinyl RPM's that are a tad too high -
Happy to share my experience if it can help someone (Joecap, maybe your no-sound issue could be related to your 2 transistors being deffective) - and happy to hear some advice/ideas regarding my RPM problem. Thanks!
Olper:
I got the same - turntable at 47RPM
I'm not expert on AC motors.. Some people recommended that changing (increasing) the value of series resistance may help. It would increase "slip" and thus make it run slower.
If this is so called "permanent slip motor", then also changing the run capacitor would change running speed.
