Just got off the phone with GC and thought of this thread. I had looked online and found the tubes I needed (you may have read the thread where I lost a tube in my SE50 and was trying to see if it was a preamp or power tube). I called my local GC just to see if they had any in stock. I have what I need except a 12at7/ECC81 to troubleshoot the preamp with.
Phone rings: "Uh guitar center..."
Me: "Yes, I would like to know if you have a tube in stock. I'm looking for a 12at7, NOT the 12ax7. Do you have one?
GC: "Uh, hold on..."
...minutes go by...
GC: "Uh yeah, we got em..."
Me: "Great, can you tell me how much one costs?
GC: "Uh, I don't know man, they just handed me the phone."
Me: "I suppose you have the 12ax7 as well right?"
GC: "Look, I just started work here man..."
Me: "Thanks, bye"
