ok, i was reading the following page about 6973 tube characteristics:
http://www.nj7p.org/Tube4.php?tube=6973

let's say i have push-pull amp with plate voltage of 380 using cathode bias resistor, than according to the data, the normal operating plate current at zero signal should be around 50ma?

i thought that was little high but what do you guys think?
did i read this data right or did i miss something?:headscrat:headscrat

When datasheets list operating parameters for push-pull circuits, the current values are for the two tubes together, so that means 25mA/tube.:thmbsp:
