[QUOTE="Ufudu, post: 645573, member: 16901"] Ah, looks like the heaters are different, but curves look similar? And the 12BH7? I was just interested in finding a Spice model to see how it simulates. The 12BH7 Ayumi spice model shows pin 8 of the input tube at 4.3V (i.e. 4,3mA bias current) and pin 3 at 112V (i.e. 6.22mA) for the above circuit. (which differs significantly from the diagram above) It also predicts 0.5% THD at 1V peak input at 1kHz and 0.05% at 0.1V (at the output of the phase splitter) Quite a nice looking tube, is it commonly available?
