Default Marshall AVT50H

Need help troubleshooting a Marshall AVT50H. Very low volume on either Clear or O/D with Volume and Gain pots all the way up. One set of PCB mount LCDs operational - more gain, more light. Other set ... nothing. CD in and Headphone jacks don't work either. Fuse OK and tube replaced. Any ideas ...

Thanks -

Yes, turned out to be the power amp. Audio Electronics/Dallas replaced it for me and it works just fine. Marshall has a three year warranty (which I didn't know) so that was even better ...
