Removed the 680 screen resistors, wattage into 16 ohms is 11.3w. Plate voltage doesn't sag with signal, stays at 365. screens drop from 340 to 300. One other thing i noticed is 120v line wattage, it draws about 72 watts idle, only goes up to 73-74 wide open. 22v on cathode doesn't really change unless i go to 8 ohms. Swapped in 6l6's, switched to 8 ohms, smoked the load resistors a little, plate drops 10 volts just plugging them in, drops another 10 under signal. Line draw with 6l6's is 80 watts, goes up to 100w under signal. Cathode is 25v, plate 355v.
