Thanks, I enjoy them very much.
Jef just retired and no longer has a website.
He's still fixing any of his amps of course and might be talked into building something interesting...
I can give you his contact info if you need it.
Lance stopped building a while ago but recently started again "for fun" when inspired.
I saw a couple of his amps on Audiogon this summer but don't know if they sold.
He sells on Audiogon as "kqvkq9" and still writes the best ads in audio!

Lance's email but it the same as the email given at the end of the Dick Olsher article on "Master Builders".
Cheers
