Thermal runaway for BJT's is a big problem when they are paralleled (hence the emitter resistors in high current power linear supplies) because in getting hotter one will prevail in low resistance (due to manufacturing tolerances) and start to take more current so getting hotter so taking more current and so on.

mosfets don't suffer in this way so are easier to parallel

I calculated power dissipation too late, after everything was burned :D


There's a difference between "turning a reflector" and "turning on a reflector" (or "turning a reflector on"), even in your country - isn't there?


You're right, that's happen when you're translating literally ;)
