    Tube vs. Solid State distortion

    The classic topic, tubes vs. solid state. /lol/

    Tube Amp Distortion.


    Tube amplifier amplifying a 1khz sine wave.
    http://hem.passagen.se/ebcpecz/Tube/...1khz_sinus.jpg

    Clean signal just like a solid state amp.

    Tube amplifier over driven into high distortion.
    Look at the shape of the sine wave, it's mangled.

    Solid state amplifier clipping
    http://en.wikipedia.org/wiki/Image:C...A_5ohms-1-.jpg

    The more you over drive the sold state amp the more it starts to look like a square wave.


    Here's another where the tube amp is operating cleanly and as you over drive the tube amp,
    the sine wave becomes mangled and eventually looks like a square wave if you over drive it enough.

    Re: Tube vs. Solid State distortion

    so whats this all supposed to mean to us?

    from what i can tell, tube amps can get square waves jsut like solid state, just a different kind of clipping?

    It means nothing.... Some people like to play mother bird....

    Tubes DO sound different than solid state, it's not better or worse just different.

    The proper saying is.

    Tube amplifiers can sound different or the same as a solid state amplifiers
    depending on it's used.

    Tubes clip less elegantly than a SS amp....but clipping is crap either way lol.

    I would rather have a rounder distortion wave than a square distortion wave. Nothing like throwing DC at your system....

    Your System Normally
    Your System ON DC

    That is the comedy. A low powered tube amp can be over driven easy into
    excess distortion. A high powered SS amp will still be operating in the linear
    region offering no excess distortion. Even though the tube is clipping more
    elegantly, the SS amp offers no clipping. Which is better? /lol

    I understand the DC analogy but technically it's not DC. DC = direct current
    or constantly flowing. Clipped signal can't be DC, but I've often referred to it
    as pulsed DC, but that's misleading too.

    On the other hand, lets say you live in the world of Dungeons and Dragons
    and you are a Liche Lord and you cast a spell called 'Time Stop', that clipped
    signal may be DC for the duration of the spell or does current stop flowing?
    :unsure: If current still flows under a time stop condition, then an AC sine
    wave could be measured as DC because you captured the voltage at that
    particular time and it's held there. /harr harr

    It's not DC since the signal is still oscillating.

    Re: Tube vs. Solid State distortion

    But, it is still flat and constant for a considerable amount of time, which makes it DC. I still call it throwing DC. You can call it whatever you want, but it's still DC. And DC+speakers = bad news...
