Something is shorted, although 11 ohms is an odd reading (most horiz outputs short to ground at an ohm or under), but the transistor remains the most likely cause, particularly with a punctured splitter spitting high voltage around.

Remove the transistor's 1/4" screws and remove the transistor by wiggling and pulling upward. Careful if you have to pry because there's a thin mica insulator between the transistor and the frame that can be damaged.

With the transistor out, check the resistance from the metal case of the transistor body to either of the two leads. If you're getting that 11 ohm or under reading, the transistor is bad. If the transistor reads the same as open leads, the problem is elsewhere.

In any case, an 11 ohm reading from the collector case of that transistor to the ground frame means the breaker will trip immediately.

EDIT: your DMM doesn't use the Fluke style "OL" to indicate an infinitely high (open) value but uses a "1" two places away from the decimal to indicate an "open" condition. Same thing, different display method.
