Ignore that fuckwit Turner's advice - for headphones you only need to supply 1/10 of a watt at most, any more will cause hearing damage. Matching the tube to the headphone impedance is simply crazy. Just connect the phones ( 30 to 50 ohms) to the 8 ohm windings of the OTs. A lightly loaded tube output stage will have lower THD and wider high frequency range then when "matched." ........... Phil
