i just bought 4 mrf477's from a guy in cali, the transistors have a green dot on them, can anybody tell me what the dot denotes as the ones we got here usually had either a k or h on them, i am hoping they will work in the lincolns and jacksons, if not i need to look elsewhere for some more, thanks
