Vox AC30/6TB Normal channel power loss
I just recieved my brand new AC-30/6TB. The sound is everything i hoped for, however yesterday my normal channel which is my preference suddenly started getting lower and scratchy i was freaking! I checked all cords and effects but it led back to the amp. the other channels seem unaffected I turned the amp off then restarted it and it was ok for a while then it happend again. If anyone has any insight about this  
: i would appreciate hearing about it before i send it back. I would also any help with the problems associated with the Vox Cambridge 30 reverb twin as I have one of these also. Regards Mark Valentine_

check the tubes to see if they are in place securely. while it is running see if the output tubes are turning red. otherwise call the company

Hi mate check valve sockets if you can access them. gentlty reinsert if possible does sound like dud valve or cold joint.

Mine did the same thing after a few months, and I traced it to a power tube coming loose. The tubes are held in by some flimsy wire retainers and mine had vibrated loose. It could be a loose preamp tube, too, that only affects that channel. It is a pain in the butt to get in there, though. You have to drop the chassis out. Good luck.
