Deve, we all need to realize that this post was about helping a guy stranded on the road. You started asking questions and making comments and caused members to try and answer you. He has a 57 and he has a ballast resistor.
I should not have switched over and tried to answer your questions. You should not have switched over to advising AD and pre AD about bla bla. You should have started another post. Lets drop the back and forth, me included. TC was trying to straighten out those who were trying to straighten out. Poster is satisfied. Done deal. If you can please delete your previous "DON'T KNOW" post I can delete this.
Your self promotion in your signature can go in your profile as homepage info or in tip section tips. Would that be more discrete?

Right is right, even if everyone is against it, and wrong is wrong, even if everyone is for it. - William Penn
