It's not a cal issue. Unless the thing is busted, they all tend to sit in the same place setting-wise [provided the gain and comp/lim switches are set the same, obviously]. That's been my experience with the ones I've come across in my travels. The only major difference depends on which optos are in the unit. I'm not an expert, but I believe there were two different optos -- one with a little faster response than the other. And then there are the rebuilt optos, which fall somewhere in that spectrum. The mod [well, the one done to my LA-3's] is changing R14 to 47K from the stock 220K.

hope this helps...
