Hi, I've had my Spider II for well over 10 years, but it won't output to the main drivers, only to the headphone jack. The main drivers pop when I turn the amp on, so I know there's at least some connection.
I've tried resetting the amp's settings (losing my precious settings in the process, booooo), but this hasn't fixed it.
I'm relatively experienced in electronics, so where would I begin looking? I suspect this might have happened when my cousin's 3 year old kid was playing near my amp. I think he might have plugged my guitar lead into both the input and output jacks. Is there a fuse or something I should check?
