    hi guys...

    if i didn't know the load in ohms of a head, would it be possable for me to work this out with a multimeter?

    what is the head ??

    theres no specifics, it was just really for future reference. just wanted to know hoe you could suss out the load really if its not marked anywhere.
  4. Then you find out

    Is it a tube or SS amplifier?

    Typically a valve amplifier will have an impedance switch or different outputs for different impedances.

    With an SS amp, then yeah, it will run differently.

    However, a load is what the speaker represents, you cant just see what load an amplifier needs by plugging a multimeter into it, infact, if the amplifier is on that would be hell of a dangerous!

    so is there no way of judging what load a head could take unless its written on?
  6. It should be written on it or if not look up a manual.

    If its a solid state amplifier you are generally fine aslong as its 4 ohms +

    Heads don't have "loads" as you describe, so there is nothing you can measure. Solid state heads have a minimum load in ohms that they can drive, but that's not the same. Tube amps have transformer taps for various load impedances, but once again, that's not the same thing . . . .

    there are only a few that wont go below 8 ohms ... most will go to 4, and more and more are going to 2 ohms ... bottom line ... ask on here ... somebody will know what you have ...
