Headphone Out works but not Speaker Out

[jgeppert]

So I just took my JP2C and 2x12 cab on a 400 mile drive from my parents house to my own. Now I’m getting no noise at all from the speakers. Switched speaker cables and still nothing. Tried plugging in headphones and that seems to work. I’ve already tried making sure the power tubes aren’t loose and turning off fx loop and reverb, to no success. Switching the speaker on/off seems to do nothing (except make the headphone signal louder??). Anyone have a similar issue or know of any suggestions?

Can you try a different cab? Maybe something came loose in the cabinet?

Do you get any sound with the XLR out? (Turn speaker off before trying since the amp power section could have an issue). If you do get sound out of XLR then the amp itsslf is probably fine.

Did you try the 4 ohm tap to connect the cab (assuming cab is 8 ohm this is a safe mismatch).
