thermal heat doesnt seem to affect it too much... I applied a blow dryer to the T4 and could get a shift in values...from .08% to about .18% but setteled back down to its home base in about 10 seconds once the heat was removed..
I am thinking this...
it might be wise to provide a space of ventaltion on the top to allow breathing room .. not that you would necessarily hear that amount of distortion but im sure squeezed in a rack the heat would build up and shift the THD values on the LDR's

I must admit that this is rather more along the lines that I would have expected... and to a certain extent I'm sure that batch purity would affect these figures too. As for the idea that they alter their characteristics and settle over time - well why not? They wouldn't be the only devices that appear to do this, would they?
