    Under the auspices of there are no stupid questions, how do you use the headphone out on a PF800 without the signal coming out the speaker cab as well?

    Never mind. If all else fails, read the directions. According to the manual you just disconnect the speaker cable.

    LOL! That's why they put 'em in the box!

    It's always good practice to turn off the amp before pulling the speaker connection.

    ^ Agreed. Even I didn't need a manual for that. ;-)

    Personally I feel you used common sense in asking a question about something you’re not sure about. :D

    When you've seen it all on TB 20x over, some of us don't take any chances :D

  9. Hey All,
    I just got a PF800 and had a similar issue (i.e. sound continues through cab when headphones plugged in). Since this is my first cab-amp purchase, and I'm still trying to not blow anything up, I'm curious about disconnecting the cab from the head. I thought you were always supposed to have a "load" connected when the amp is on. Is that not true? Can I unplug the cab and still have the head on? I thought I read that this can cause the head to smoke/malfunction.

    Thanks!

    If you'll read my original post, the only way to use the headphones is to disconnect the cab. So, yes.
     
  11. Yes. I get that.
    I’m wondering why there are so many other threads about smoking amps that malfunction when the cab is disconnected.

    Was that only an issue with older heads?

    Thanks!

    I don't think it's an issue w/ tube heads, IIRC. Not sure if class D amps are different or the fact the pf800 has a headphone jack that negates any problem running an amp w/ no speaker load.

    Generally, tube amps (tube power amp) needs a load to prevent damage.

    Generally, solid state amps (class AB and class D) do not need a load.
