Re: I want to build a stereo headset valve amplifier
You only need a few 10s of milliwatts in order to drive your headphones to deafening levels.
With that in mind, there is no need to build a valve amp that can output several watts to drive your headphones. In order to safely be used, you would still have to waste nearly all of the 3 or 4 watts that a single ended EL84 or 6V6 could provide.
