Hi, and cheers.
After posting the thread I discovered the search function, and the *handy* "similar threads" links at the bottom of the page!
Its amazing what you see when you open your eyes and look, tis great to find such a usefull resource - kinda how I envisioned the internet should be used. I may even be able to find out enough in order to keep my quiver of old skool subs alive a little longer?
Anyhoo, cheers again.
