I know nothing about self made interconnects but I have a 45A and love it

Not to change the subject but Outlaws PSC's are excellent if you need some dig coax connections. They double as excellent cables for component video as well. They are cheap by some standards and are of excellent quality. Their PCA's are great as well. Hell, everything from these guys kicks ass!
Good luck though, hopefully someone can you help you out more then I did. Out of curiosity, i will check out the page you posted.
