I'm putting together this PSE amp using the 12B4 doubled up running into an OPT at 2500 ohms. With only 170VDC for my B+, I get a really 'steep' loadline for the 12B4......my question is 'How does one do the DC loadline for "twin" ouput tubes.??? I,m trying to get a handle on how much current each channel will be drawing.

Slightly OT, how does one go about calculating the bias for three DIFFERENT power tubes in SE, like Palmer Triple SE
I think the OPT has three separate primaries, so each tube type could see the correct impedance, is it just that simple?
