    How early do B15's usually break up? I just picked up a B15s and once volume goes past 10 o clock, it's got a very heavy distortion on it (almost sound like i'm running a tubescreamer or something). Doesn't seem right to me, didn't get a chance to dig into it much, going to run it over to my tech tomorrow to have it gone through anyway but was just curious if this was normal.

    About ten o'clock with a P-bass for me. The Ampeg book makes mention of it breaking up early - well below noon.

    Ya, could be the output of the bass making it break up a little early, but the 10-11:00 mark is generally where they start to break up. If you think you're not getting full clean output, best run it by a tech for a once-over.

    I did ran mine at full for +- an hour and he (she?) didn't like it.
    Did that to have a distorted sound . Not a good distorted sound. Not good for the amp.Had to change the tubes.....

    Also one of the wire that links the paper cone of the speaker and the connector dropped off. I have the orinal , square magnet model. (too much vibration? )

    Lesson learned: it's a low level amp. (mine anyways)
