RE: How much actual mercury is really in one of these tubes anyway?

I know some of the bigger tubes had more.
It could also be that some brands had more than others.
I have about 20 or so of 872a and some have alot more Mercury in them than others.
Even when it comes to the same brand, I find it can vary.
Some old GE 872a had much more than the later GE 872a.
Same goes for 575a tubes as I have quite a number of these as well.

Not always but I find alot of the earlier tubes had more Mercury.
