Thanks, the pain is stopped but I've got second degree burns, but SAE says to use a 50 frickin watt supply into .5 ohms.... that was a 9 watt supply, or about that. I really expected that the BJT wouldn't get that hot but instead the transformer would be the main power consumer. Then again, the transformer is much larger, so it wouldn't get as hot as the BJT.
I was playing with the amplitude on the signal generator though, and found that when the signal amplitued was from 0 to x, I got a really distorted signal from the output of the transformer. From x to y I got a clean signal, from y to z I got a somewhat distorted signal, and from z to max I got a clean signal again.
I neglected to turn it back down to the x to y range and instead left it at the z to max range. Don't know if that is why it overheated or if it would have overheated if I had left it turned down.
No matter what though, I was stupid for touching it, even if it was an accident.
