It all depends on whether you are talking about northern or southern and winter or summer. In Texas when it is near to 100ºs, the cartridge is ready to go. In the winter, with the coldest temperature set at 72ºs, it may take on cut.
How long before your cartridge warms up?
Wondering if people would share how many sides of a LP must be played before they believe their cartridge has warmed up and is on "full boil" so to speak. My Ortofon MC Anna seems to like about 2 to 2.5 sides of an album (e.g. 33.3 rpm) before it really comes to life. This is something I am just starting to notice as I am fairly new to analog.
