Hello!
Which tube is equivalent to 1/2 12BH7?

But no matter how how high the value of BH7 RLa, the triode still has to swing the rather high anode swing, and my load line analysis reveals BH7 is better than AU7 at this job.


probably because it was designed specifically FOR that (vertical
amplifier/oscillator in a TV, requires large linear region for wide
plate voltage swing)

makes sense to me. I'll consider this tube as a driver for beam power
tubes in the future.
