Is it wow repeating at 1.8 c/s, or flutter similar to that heard on worn cassette tape recorders? You can test your system by using a test record having a 330 Hz track. Human ear is most sensitive to frequency variations in this range.

1. What deck is it?
2. AC or DC motor?
3. How recently was the bearing cleaned and oiled?
4. When did you replace the belt last?
5. Which arm do you use?
6. Can we see some pictures of your deck and arm?

It could be any myriad of issues, sticky bearing, slippy belt, stiff belt, failing psu, poor levelling, cartridge failing, arm misalignment, poor recording, off centre record etc etc etc.

Answer some questions first then we'll not all just be reaching in the dark for answers based specifically on our experience as opposed to assessing the potential causes in your set-up.

ps, a strobe disc and a laser tacho are next to useless for identifying the causes of speed instability, they are great for checking long term speed stability and drift but very poor at even indicating the presence of high speed instability.

Again, we're losing sight of the obvious: borrow another turntable and play the same record, which exhibits the "problem". In so doing, you'll be replacing the entire subsystem, with all the theorized "problems" in one fell swoop.

There are exactly two results: the "problem" goes away, or it doesn't.

IF it doesn't, then the "problem" is imbedded in the recording.
If it does... then sacrificing chickens at midnight is advised, along with throwing salt over your left shoulder.

I predict the "problem" will remain, and this will isolate it to your afflicted recording.

I have a copy of James Taylor, Sweet Baby James that has a bad flutter or pitch variation problem. As you mention it's most noticable in quiet passages and particularly during the decay of guitar music. It's definitely a problem with the record itself. None of my other records exhibit this problem. My solution is to play the CD instead. Maybe your record is bad.

I am awaiting a friend to come & have a listen & Ill get a second opinion. I've got a sneaky suspicion that 10 years of listening to music with ear buds on a phone & nothing else, has left me forgetting what the details in music are supposed to sound like. I know that sounds strange but I think it might be the case. Plus, I'm obviously paranoid & neurotic.

@SQ225917. Turntable is only a cheapish Clearaudio knock off & I think that's causing my neurosis. There's no way its as bad as I think it is, bearing is fine & spins freely, I checked the records I was playing to make sure they're centered, motor seems to have plenty of torque & I've checked the belt for slippage.

I did think that strobes weren't really that good at picking up tiny variations in speed but if I touch the platter/belt enough for me to audibly notice it, the strobe does move move too.

Like I said, I'm beginning to seriously think it's me worrying that I made a mistake, the notes I hear wrong, maybe, are supposed to sound like that & I'm misinterpreting what I hear. Second opinion will come soon & I'll post back if I'm mental.

@oshifis, szia. I will be getting a test disc at some point to further my decent into lunacy, rather than just listening to music. On the whole this turntable actually sounds pretty good.

OK so you are going to get sorted soon.

Here is the link for it 21 days free trial should do.
Virtins Technology: Turn a PC into Virtual Instrument - Home

Just one thing came to mind
I had Salas Simplistic and is a really good phono stage but I could not listen to same records anymore.
could this be the case?
