I find it interesting that some people have good luck with HC-4 and HC-5
elements with not mods or preamps, while others have problems getting
enough drive even with mods. Is there that much variation in the
elements, the KSB2, or both?

Thanks for the info, Gil. I've been worrying that perhaps I have a
problem with my KSB2. It's reassuring to hear that I'm not the only one
who couldn't get it to work even with the mod. 

I'll build the preamp and see how it works. I'm pretty busy at work for
the next three weeks or so, so I don't know when I'll get it done, but I
will report to the list with my results.

Yet another reason to like CW... ;-)
