WARNING: Tube/Valve amplifiers use potentially LETHAL HIGH VOLTAGES.
Building, troubleshooting and testing of these amplifiers should only be
performed by someone who is thoroughly familiar with
the safety precautions around high voltages.
I have a pair of Sennheiser HD600 headphones and would like to try them with the tube amp I built. The amp is a SE 2a3 using a Plitron audio xformer with a 8 ohm output impedance. The headphone Impedance is 300 ohms. Not sure if you can just hook up that load to the amp.
I would put an 8 ohm resistor across the output. Then connect the headphones across that. You don't need much wattage for the resistor because your ears don't need it. And shouldn't get it either.
