    I run a tweed champ (clone with SF Champ OT) with a 8 ohm speaker?

    Why?.....is the Champ a 4 ohm output? If so, there will be a loss in volume and maybe loss in tone. It should not damage anything, if that's your question.

    Yup, I’ve run mismatched ohms a lot. Still sounds good. As long as the amp is just one step down and not the other way around, you’re fine.

    This sounds like my unfortunate winter-time experiment

    I burned up a voice-coil in a jbl spk 16 ohm, after plugging into a 4ohm output amp.

    minimum $80 re-coil /re-cone fee.

    back to stock - which it was designed for and shipped with.

    welp. . .

    Deeve, I had a JBL D120F marked 8-16 ohms, the DCR was around 12 ohms as I recall. I used it in a couple of 8 ohm amps, (it sounded glorious), but went to lighter speakers in both.
    I never got a straight answer as to why they were marked that way!

    And for the 2 seconds before it flashed, mine sounded pretty good too . . .

    In theory it will work, but in reality my experience is that the lower the wattage, the more the mismatch effects tone. Also, Champs are not terribly robust transformer size, so there may be some risk to running it long term. Short term it's fine, I've tested many 8 ohm speakers with a Champ.
