don't laugh too hard, In the ARRL handbook it claims 8 watts audio from an 12AX7 in zero bias class B push pull into 8000 ohms. I have never understood that one, if you look at the currents stated in the book, they seem pretty high for the tube.PJ
Oh, I don't know... 250Ep into 8kOhms is 0.03125A (around 30mA) 250Ep * 30mA Ip = 7.8125W --- -Geoff/W5OMR
