    I want to build a headphone amp to connect to my laptop's audio
    output, and thought a tube based one would be a nice change from all
    the IC driven ones I've built in the past. I would prefer a simple one
    with low cost components, and low voltage operation, if possible, and
    no more than 3 tubes. Any tube type will do.

    Thanks

    OH WHY ?

    Why would you want to degrade the sound so faithfully preserved today
    through ultra-accurate high bit density recordings at the final listening
    stage.

    Why not just listen on some ex-army headphones ? It'll do the same thing.

    As good a way as any to get a crap sound.

    Try to get hold of some nuvistors.
    Googling for nuvistor produced a nice hit of
    explanations and designs.
    Oh, and start saving up some money, they are expensive. ;)

    45 to 90 volts is OK by me. It's voltages higher than 200 volts which
    I didn't want to use

    I looked at your link and thought, how about an amp for electrostatic
    phones? I found the Gilmore amp indirectly because of you. Thanks

    I love the old tube equipment, radios, amplifiers, etc. I don't care
    for best sound quality either.

    Excellent advice.
    You haven't 'lived' until you touched the anode cap of a color TV
    horizontal output. The anode of the CRT isn't much fun either.

    By "low volltage" I meant any voltage below 160v.

    I have a stepdown transformer to run my Zenith tube radio. If I
    recitify this with a silicon diode (or tube rectifier) I get around
    160 VDC. Is this right? I want to run the B+ without a transformer if
    possible, much like my AC/DC Zenith which has around 160v B+. Reduced
    power output shouldn't matter since it's to be used with headphones.
    Gotta search for a suitable circuit.
