[Amps] Verify "Q"

[Joe]

Ok,

Lots of reading, LOTS of help from others here. This should be the last 
bit of questions I have the need of help with.

When doing the like reverse plate load simulation test.  I have been 
told, and have read, both things when doing the test, some have said to 
lift the plate connections off the tubes.  While others say that they 
need to still be connected. So what way is it?

What value of "Q" should one desire to have?

And once the amp is thought of to be set up with that desired value of "Q"

Is there a way to measure this value of "Q"?
