Transistors: Why "Q" and not "TR"?
 

I can understand not using "T" beause that was used for transformer, which is a heck of a lot older than transistors. But where do they come up with using "Q"? I suppose a TO-18 case looks sorta like a letter Q but it just seems silly. The Japs used "TR" in the old days and it makes sense so I use that.

TR was already in use for "ToweR" and Q hadn't been used yet.

It's silly not to use what everybody else does...

I think it is "Q" because when you do the DC bias, you find what is known as Quiescent point. Hence Q
