Ill pass on your trolling and lack of any technical points to refute
any of what I wrote.
Just some idiotic crap about plug catalogues you dont have the sense

Make your point or admit your dont have any argument to dispute
anythuing I worte, not one line of it.

And you dont have the sense god gave the common dog to figure out what
