Howdy all. Not sure if there is one available but I thought I'd ask here. Is there a cheat sheet that will tell you how much current a 12AX7 (or 12A?7 of any description) voltage amplifier will draw for a given plate voltage and cathode resistor?

Maybe I'm clueless and can use the standard charts for this but it strikes me that one can only use them if its fixed bias you're using.
