Why is my turntable's frequency response now dropping off?

wow , that is a lot! I posted a FR vs T somewhere here , from a Japanese document. Maybe you can find it, I am too busy , wife is on the phone so here is one,..

Wow! I never know temperature could have that effect! But I sure don't miss analog vinyl!

Yes, before posting my original post, I read online about temperature changes being able to change the frequency response, and I came across this chart, but I was honestly very skeptical, like I wrote in my original post, since there's so much BS floating around online in the audio world.

Temperature changes can also require a minor change in tracking force sometimes, at least in my experience. I think there was a paper about it on some Japanese site

My indoor temperature is about 22-23 in winter and at most 24-25 on a hot summer day, so not much of a problem

7-8 degrees C diff should give quite some effect with your cartridge.

That was the one i could not Find.
Next , i have to Get out A hairdryer and heat the cartridge before the frequency sweep..

Beware you don't put a a hitch in your giddy-up !

Fascinating, and also a new response to those that complain that AT carts are too bright, just drop your room temperature by 10 degrees and it'll sound great!

I reckon a linear tracker would track that.

It just might, but still reveal a little warp wow into the sound.
Does the tracking speed/needle ips increase or decrease as it goes uphill on the warp side?
My math is failing me tonight.
LOL

I can't say precisely, but it could be 7-8 degrees difference celsius.

That’s a lot.

It'd sound horrible for sure. But I have got a few linear trackers (ultra lightweight, short arms) that seem to track just about anything.

I had a horribly warped Tears For Fears LP that physically threw conventional arms off the record, but a little Onkyo Linear tracker with a 3/4 gram tracking weight cartridge played it. I looked at it and went WTF?

Still sounded like ass but it tracked it.

I don't doubt it. My H-K ST8 with a Stanton 881S, was the best tracking SOB I've ever seen. (trash-can the dust brush).
It's design was an exercise in low mass tonearms.
I had the idea of removing the sliding weight from the arm to further reduce moving mass and just set tracking force with the rear counterweight.
Never got around to it before I lost all interest in vinyl and sold everything.
