i think that those impedances should have B+ voltages associated with them, otherwise they don't tell a whole lot imho....
sounds like a good idea...so does such a chart exist? I posted a Groove tube chart with different bias voltages for different type tubes in another thread. So sure, a plate voltage chart should be floating around somewhere.
it says on the charts, primary impedances, so i assume they are plate to plate impedances, what caught my eye, 2 x kt66 8000 ohms, must be either lower powered or high B+....
Is that across the whole PP primary though, or from each leg to the centre tap?
