Blues Deluxe Reissue problem :(

Last week I started having problems with my BDRI. It'll be fine for the first 15 minutes or so of playing but after that it just cuts out and won't make sound until I wait a bit and try again. It seems like it is overheating but it's never had that problem before and I can't find any information on the internet.
-I bought the amp new in September 2012.
-Last month I replaced the stock speaker with an Eminence Cannabis Rex.
-In doing so I had a hard time returning the circuitboard to its place since it is made to fit very tightly in the frame. Some of the conductive tape on one side was peeled off and got folded over in the process. This is the only thing I could think of that might be the problem.
Any help?

i would likely place a bet on power tubes.

Thanks guys. I am most certain it is not the power tubes since there wouldn't be a total loss of sound from just one going bad. On the odd chance that they both went bad at the same time, it would be even weirder if the problem was intermittent.
I got a recommendation to check the speaker cable first and then check the solder joints. If that doesn't work, I'll try a new set of tubes since I was going to replace them soon anyway.
I'll keep you posted.

so come here and ask a question and don't listen?

dying powertubes fade in and out and will go for no volume. that is probably the most common sign i see. they are not always consistent when dying either.

worst case you buy power tubes and have backups, but i highly doubt that would be the case.

i am assuming you put the proper impedance speaker in, right?

Actually one failing tube might do exactly this. If one fails the FBD goes silent. Fading in and out is a common indicator of power tube issues. Cold solder joints have also come up from time to time but these amps are really pretty bulletproof.

I'm just trying to rule out the things in an order that would save me money. The speaker cable appears to be faulty so I'm dealing with that first.
I talked to a Fender technician and he said the tubes were unlikely the problem. I still said I would check them as a last resort. I'm not ignoring anyone...
I'll double check the impedance when I get home too.
Thanks.

I replaced the speaker cable and didn't seem to have any problems for awhile but recently the problem came back so I'm not sure that fixed it. I ordered a new set of Tung-Sol 6L6GC power tubes. I'll keep you guys updated if that seems to fix the issue.

I replaced both power tubes AND all three pre-amp tubes and there is STILL a problem.
Anyone got any other ideas? I'm stumped.

Could be a component heating up and lifting off the board. Could be the output transformer on its way out.

Take it back to your fender technician, it's very hard to diagnose problems over the internet once they get past the usual suspects.

I agree it's time to take it to a tech.

With a tube amp the first thing to do is ALWAYS check tubes. That's the most common problem. This sounds like something else inside either heating up and failing or failing in general, since you ruled out tubes. My Super Reverb was doing the exact same thing when I got it, used from a relative who bought it new in 1973. It turned out to be a capacitor failing once it got heated up. And the shop he took it to had missed it...I found it by doing a complete cap job just to replace all the 40 year old ones inside and upgrade the cheap ones CBS used when they built it. A failing output transformer can cause the same thing, but I would be more likely to believe it would be a component failing once it gets hot. Capacitor would be my guess, but that's just a guess.
