Hi,
Recently I've bought used ART Tube MP Studio V3. The power comes when connected to 9v adapter and I can hear the small amount of noise when I turn the output level to maximum. But input signal is not detected, no sound come out . I've tried with microphones and guitar by using different cables. VU meter is not moving and no sound out. Is it tube problem? Can I fix it by replacing tube? Or Is there any other possibility of that problem? Please advise. Thanks.
