The 6L6 puts out about 2.5 times the power when operating as a single tube Class-1A aplifier. Other characteristics are also different. Yeesh! That is not good at all! That is a very misleading number in that case. What about the 25L6 then? I have pitched a lot of 25L6 tubes over the years because they showed low transconductance compared with a 6L6. Personal opinion of mine...I think the * manufacturers* intended a 35/50L6 to be a DESIGN replacement for the old 6L6 as applied to AA5 50s-60s radios. Walks the same walk but its a 150 volt tube. I pulled out the HB-3 for this and wow... it sure IS different. Only 8.5 watts dissipation, versus 14 for even the baby 6V6. No question about it....its not very closely related if you're looking from a conventional 6L6 perspective. 25L6 is sort of a different animal not related to either of the two. According to the HB-3, the 25L6 has ten watts which is a bit more than the 50L6. Mine does not have a page for the 35L6 but there is a note saying the 35B5 is an equivalent. --scott -- "C'est un Nagra. C'est suisse, et tres, tres precis." |
