Gentlemen, thank you all so much for your warm welcome to the forums, and the information you have provided. You guys are the best! I have been reading here off and on for a couple of years now learning a lot in the process, and your collective wealth of information and willingness to share it is truely outstanding! Brad, thanks for your explanation. I guess these tubes look far different than they really are. Yes Drew, I live in Lee's Summit, thank you, sir! Good to hear from you as well, Chuck!
