Can a horizontal TV be used as a Power Transistor?

(Invalid img) Hi friends, I'm going to build a regulated source with lm317, use a power transistor, but I don't have those, I can use the Horizontal of a Old TV?
If not then, any of these:

Oh something similar, the polarity must be NPN
These transistors are

  • The D1294 is worth it if you don't ask for more than 5 amps. Keep in mind that it is a darlington NPN transient.

Hello friend, it will all depend on which transistor you will substitute for the horizontal one, so that you will use the source and what this transistor is doing on the source you want to assemble. If you share the diagram and the model of the power transistor it would be excellent.
