Need help with my Supratek Chenin

I've had my Chenin for about two years and have enjoyed it. Unfortunately, about two weeks ago, I turned on the preamp and my CJ solid state power amp at exactly the same time. The tube in the preamp power supply seemed to get really bright like it was about to explode. I then turned off the unit. When I turned it back on all the preamp tubes lit up, but no sound came out of my system. Mick, the owner of Supratek, told me to replace the tube in the power supply, but that has not helped. Anyone else have any ideas as to how to fix? Do you think that the incident affected the amp and that the amp is the problem?
How about the fuse?
The fuse would be my guess as well. I would check the fuses in both the pre and the amps.
