Anyone adjust cart set up due to ambient temperature changes?

My cart body was dragging slightly, so I contacted the manufacture. It is 2 years old.

I got a response within a few hours, and they asked if ambient temperature had increased by more than 4-5 degrees recently.

It has - where I live usual summer weather is a bit late, and the max temp in the house has increased by about 8 degrees. (we try to avoid using aircon).

They recommended decreasing normal down force from 1.9g, to 1.7 or 1.5 (min), and increasing VTA slightly.

-0.2g & + 2mm VTA solved the issue. Back in business sounding great.

It was new news to me and I avoided an overseas evaluation and possible repair.

Anyone else adjust due to temperature changes?

Interesting! By 'dragging' you mean the rear of the cartridge touches the surface of the LP?

I have a grandfather clock made in 1759, and it was not fitted with Harrison's new-fangled gridiron pendulum (1726), so I have to adjust it as in the heat of summer it can lose 1.5 minutes a day.  Once adjusted it keeps time to within 10 seconds a day

What kind of cartridge was this? The temps in my listening room vary greatly and I've never encountered such an issue, FWIW.

It seems the ability to tag members isn’t working…

Anyway. It’s actually part of the front structure that supports the generator (if that is the correct term)

The cart is an Aidas CU Durawood Bee.
