Difference between 6JN6 (Berning output) and 6JB6 tubes?


Other than the obvious difference in basing (the 6JN6 is duodecar, the 6JB6 novar), is there ANY significant difference between the 6JN6 and 6JB6?

I'm thinking of cloning a Berning EA-230... which originally uses 6JN6 tubes... however, I have BUNCHES of 6JB6s, and very few 6JN6s. I also have a quad of Novar sockets... that's a plus.

I've compared what I can find for spec sheets, side by side... and for all the alignments I can find that match (voltages, currents, etc), the tubes look virtually identical, except for very minor differences in element capacitance (and the 6JB6 actually looks lower than the 6JN6, a tad).

Anyone found any differences between the two, in either practice or in spec sheets?
