Technical Difficulties Thread

Got the new belt on, it definitely turned without an issue like the old one had but then I noticed it was playing things verrryyy slow.

Ive since then adjusted the pitch control and it seems like things are running as normal but I'm not feeling like I don't have the pitch dialed in accurately. I used a phone app put the phone on the table and I come approximately close to the expected speed. How would I be able to ensure I've got the right pitch?

I'm planning to take this in at the end of August when the guy at the use gear shop is back from holiday to get it properly tuned up.

The best way is with a strobe disc. Get one that is smaller in diameter than an LP. Gently place it on top of a record on the platter. I keep an old beat up LP around for just such things.

Then play the exposed part of the record. You’ll be able to adjust the speed while taking account of stylus drag.

Accelerometers in smart phones aren’t really precision devices.

Would you still use your phone for the strobe light?

@uvwxVinyl Hold it. Does your turntable have a strobe on the platter?

Haha actually I realized that just before I went to bed by reading the manual about changing the pitch control timing belt (which ill do anyway I'm the next few weeks). Anyway the discovery helped me sleep easily.

I have 4 rows of dots on the platter and I flashed them with the 60hz and 50hz strobe app and was able to dial the pitch and verify until the respective line of dots appeared to stand still at the corresponding speed.

I think it sounds pretty good now. They said in the manual it should ideally be a light source from the same AC main so there's a chance I'm slightly off with the smart phone but I can't hear it anymore.
 
I had another hiccup today I believe it actually is indeed a lubrication issue.

The motor was getting jammed again and you could see it spinning slightly counter clockwise as it struggled to turn the platter.

I removed the platter and notice the rotor spindle also required a bit of an effort to spin by hand. I wish I took pictures when I took it apart but I removed 30 and 2 as shown in the service manual below.

I noticed there was some oil still in there so I twisted it a bit so that the rest of the shaft would get greased. When I put it back together I could spin rotor really smoothly by hand.

Anyway everything is working again now. I guess I should have it properly lubed in the service as well. I don't really know how much or what I should put in there, so I guess I'll leave that to the turntable service guys. The new belt has helped, I do notice the wow platter to have gone away but I assume the reason for the problems in the first place was dried up lubrication on the rotor.

Im an Engineer but I feel pretty pleased taking this apart and solving the issue myself. Learnt a lot about my turntable this way and its pretty cool to see how great these things were designed back in the day. You don't see service manuals like this these days either.

Good news. Yes, all turntables require periodic lubrication.
 
ok, friends, i have a problem with my turntable and I need your help.

So, I am using an u-turn orbit with an ortofon 2M red. The platter is the standard wooden one. Before I had the u-turn, I was using a pro-ject essential ii with an ortofon om5e, which worked completely fine! i had no problems with that pro ject TT until i ended up damaging the tonearm by mistake (my own fault).

so anyways, back to the matter at hand, I have had my current u-turn orbit since i think January of this year. around March, the cartridge/stylus has not been working properly bc it now stays trapped in loops almost every single record that I play on it. I wasn't able to get a stylus force scale gauge until recently, once i got the scale, I saw my cartridge had a tracking force of 1.7 g, and after increasing it and testing it at 1.8, 1.9, and 2.0g the needle would still loop on records as if nothing had changed. it wasn't until i tested the maximum tracking force (4.2g) that the stylus would then play normally, but there is obviously something wrong happening bc a tracking force of that magnitude is not ideal at all.

what do you guys think the problem might be? i personally think that this might be the cartridge's fault, but im not sure if finding a replacement stylus for the 2M red is the best solution. i may just have to get a completely different cartridge, but if so, i would want something decent in the $50-100 price range. the belt might also need to be replaced too. lmk your thoughts

Have you cleaned your record(s) and stylus? The few times I have had loops on my uturn, it's been a cleanliness issue.

i use a dry brush to wipe off debris from records and i do clean the stylus after every use. i have a deep record cleaner, but i haven’t used it this year bc i want to change my deep record cleaning method. (but that’s a post for the record cleaning thread). clean vs dirty records might be a factor into this, but i still dont think it’s the main reason bc this problem has happened with almost all of my records, whereas i didnt have this problem with the pro-ject

ok, this sounds like a good idea. any recommendations to which one i should get?

You can do a decent job with a small bullet level and just turn it multiple angles until it stays centered always. If level is your issue it will show up on a bullet level. A bubble is good for getting the gnat's ass. The main thing about those is getting one that is truly flat.
 
ACTUALLY WAIT, I JUST REALIZED SOMETHING!!!!!!


so i live on the first floor of my apartment building (therefore, in the ground) and in late March, my complex decided to cement a new parking lot right outside of where i live. i didn’t use my TT that week, but i remember the drilling and paving was very strong and it would feel everywhere in my apt. now im thinking this might have been the thing to have done something to the TT.


edit: so upon further speculation, i feel this might be an issue that just warrants me sending the TT to u-turn under the warranty and try to get it fixed or replaced. i’ll send them a message and see where this goes

I mean it sounds like a good way to lose level...

I had a similar problem with my U-turn a year or so ago. It was mostly happening while playing the last few songs on a side (towards the center). I sent it back to them and they ended-up replacing the motor.

I have the walnut plinth and run a 2M blue
 
A question for you smarter than me folks. When I'm listening to my TT through the headphone amp, my NAD powers off periodically. It doesn't feel particularly hot so I'm wondering what would cause this.

Auto standby enabled. From the manual:


AUTO STANDBY
Auto Standby feature is an integral feature of the C 326BEE that conforms to European ecodesign regulations. When Auto Standby is enabled, the C 326BEE will automatically go to standby mode if there is no active input at current source or no user interface interaction within 30 minutes.
Auto Standby can be enabled or disabled by the following button combinations and Standby LED indicator response. Execute below steps while the C 326BEE is at operating mode.
Press and hold [AUX] button and then press Standby button. Observe
the number of times the Standby LED flashes.
• Auto Standby enabled : Standby LED flashes once. NOTE
• Auto Standby disabled : Standby LED flashes twice
