Re: Part id help

Could it be BD318 can you describe it ?
BD318 is one of those big metal round transistors with a oval sort of baseplate with 2 fixing holes

Re: Part id help

Your right - sort of thing you might buy at that price to scavenge parts off
Anyway if you can get a good picture of it we can look again

It looks like one of those 555 based for PWM and MOSFET, that is very low price.
