RE: Could it be a 12AU7?

The only thing readable on the tube is a triangle on it's right side if that makes any sense (the long side is on the left at 45 degrees, second short side is vertical) and directly after that is 1J5. That's it. The stuff above that is just fragments. Impossible to make out.

It sure doesn't behave like a 12AU7 in my tester.
