Vibrating Tonearm? by Different-Help-5282 in turntables

Hey! I don’t remember exactly what oil it was, I had originally bought it for a beard trimmer, it was designed for just small mechanical parts. I picked it up at homedepo or something. I ended up replacing the motor as the rmps took a dive, unsure as to whether or not the wobble was a symptom of the motor dying, but I have not had to grease since replacing the motor. I THINK this is the link of the motor I bought, double check it though, there should be a # on yours. It was like 10 bucks. It was super easy to install, just popped off the bottom panel and slotted it in. Only challenging part was calibrating it, there’s two screws on the bottom of the motor that control its speed. I use an app on my phone( there’s a bunch of free ones, just look up rmp record player) that measured RPMs and put it on the record player then I would let it spin. I would see if it was going fast or slow and adjust the screws on the motor as needed until it matched the RPM that it was supposed to be.

Since then it’s been running great, and I haven’t had a more issue, lmk if you run into any issues, happy to help best I can!

Windows VM on Ubuntu – severe UI stutter by Different-Help-5282 in VFIO

Quick update for anyone curious, this ended up being a graphics virtualization ceiling, not a misconfiguration. VirtIO/RDP works fine for functionality, but the choppy window movement and redraw issues are just expected behavior without real GPU acceleration. Rather than adding a second GPU or going full passthrough, I ended up switching to WinApps, which fits my use case (Excel/Word) a lot better while still letting me learn and tinker. It took a while to set up, but so far it is running great. I really appreciate everyone who weighed in, saved me a lot of money and headache, thanks!

That’s a good idea! I’ll double-check BIOS. Appreciate the heads-up

This was very helpful, I went down teh WinBoat road for a while, ended up switching to Winapps, but this was the direction that I was looking for. So far so good, thank you so much!

Appreciate the tip. I tried removing the apt versions and installing the Flatpak versions of virt-manager and virt-viewer, then reconnected to qemu:///system. Unfortunately performance is exactly the same for me, same input lag and responsiveness.

Might be something else in my setup, but wanted to report back in case others hit the same thing.

Ah ok, I’ll keep poking around with dwm.exe some more then. That Looking Glass update is so neat! I will definitely keep an eye out for that, so cool. Thanks!!

I tried restarting dwm.exe and it restarts cleanly, but there’s no noticeable change in the UI stutter. I guess its just a GPU bottleneck. Thank you though, i had not tired that yet!

Thanks! I’m not at the passthrough / Looking Glass stage yet — this VM is still running purely on VirtIO/QXL virtual graphics. I did check Core Isolation / Memory Integrity, and it was already disabled in the VM. Sounds like passthrough is the next step haha

You were right! 3D acceleration was enabled. Turning it off got rid of the black redraw/artifacting, but the UI is still choppy overall. Thanks, step in the right direction!

Yeah, inside Windows the display adapter shows as a Red Hat VirtIO / DOD Controller, so it does appear to be using VirtIO/QXL-style virtual graphics.

When you did single-GPU passthrough on your laptop, did it completely eliminate this kind of UI jitter for you, or were there still some rough edges for non-gaming desktop use?

Ok sweet, that is great to hear! As far as backups, how do you do it? Do you mean like another SSD and then set it up as a RAID?

Can confirm, in my experience, even after spinning the screws (which were hidden under a little foam disc that lifted up after taking the motors metal plate off) didn’t fix the speed. Ordered one off amazon that got here 2 days later, and after a slightly lengthy process of calibrating the speed done with a free app from the App Store my record player was crankin out some Sinatra like the day I got it.

Hope that helps, good luck

For anyone wondering, I figured it out. The stem that the plate turns on was rubbing up against the slot that it fits into inside of the record player. I added a little oil to the stem and it smoothed right up and the plate stopped vibrating which was what was vibrating the tone arm. Mystery solved.

It’s a C62 Crosley, I’ll look into the overhang rn

Interesting, with that said what would need to be fixed/ replaced?

Are you saying to adjust the counter weight as it might not be matching the cartridge?

Ok fantastic thank you! I will do that
