    Hi there,

    After a gig i noticed quite a loud hiss from my lh 1000 when i turn up the volume past 6. This happens without any cable in the input, tweeter off and is accentuated by raising the mid knob.
    I changed the preamp tube but the hiss remains. Any ideas?

    Here s a short clip:

    Thank you.
