    Ok, heres the problem: Sometimes, when i turn my amp on, i get real low volume, no matter how high i turn up. i have the tube pre amp all the way up, and the solidsate off. but when i turn the tube off and the solid state up, i get normal volume. Is this the tube going out, or what?? its a Ha3500.thanks in advance.

    A failing tube would be my guess. Might as well try replacing it--one 12AX7 isn't going to cost you that much.

    Could be the tube,
    but the solid state channel on that Head is louder than the Tube channel. (I had the Model 2000)
