The Berning 2100 and the Counterpoint SA4 both used the now ridiculously expensive 6LF6 (though it is a very nice output tube). Expect $80-$100 per tube for NOS; you have ham operators to thank for the price.

sweep tubes and audio application?
I am asking the members of the Gon what plus and minus are there with using sweep tubes {TV Tubes} in the designing of amps and preamps in audio today. I have been told they are cheaper tv tubes and last longer. I like to know if they are best at sound reproduction or just smoke and mirrors? And are their any members using them with success.I thank you all for answers to my questions
