What devices would contain a TIP31 transistor?

I have a lot of old electronic devices... Which are common ones to contain a TIP31?

The most logical source for at TIB31 for me would be Radio Shack.

Other that that, TIP31 is a standard type of NPN bipolar junction transistor used for medium power linear switching applications.
can u please tell me which transistor similar to tip31
comparatively what r the transistors similar to tip31

I've never come across one though I've salvaged some 20+ different types of household electronics. They don't seem to be too common in smaller devices now that more sophisticated means of amplification can be done so cheaply by large companies. I suggest going on eBay and ordering a 10-pack of them. it'll only be a few bucks

I'm have this one thing called a "Electronic store" that has a bunch.
