The writing on the transistor reads:
TFK
9624
and then either
BUX127 VDO
or
BUK127 VDO
We found a datasheet for the BUX127, which said it is a SEME 150W switching transistor;

As far as I can find, the BUK127 is a Philips 1.8W switching transistor.

The item is rectangular and has a 2mm hole through it. It has 3 flat legs. It's about 13mm wide, 16mm tall, and 3mm thick. The middle leg is wider than the other 2.
So, can I use a switching transistor for amplifying audio (given adequate cooling and not running it too hard) and is anyone willing to draw an easy to understand circuit for such an amplifier?
