FDP Forum / Fender Amps: 1985 - Current / New Fender Deluxe Reverb 65---loud static noise

Hello,
I recently bought a Fender Deluxe Reverb 65 from Sweetwater. Amp seemed great, but all of a sudden, it started making this crazy loud static noise, even with nothing plugged in, and all knobs on zero.

Here's a video clip:

I'd like to just exchange the amp, but unfortunately, it's past the 30 day policy they have (by maybe 18 days), so they are making me trouble shoot the amp. They think it's the power tubes.

Thanks for any help.

I should say, also, that noise is intermittent. If the power tubes were bad, would they work fine sometimes? The amp can seem fine for awhile, and then burst into that noise. Turn amp off, turn back on, and it's back to seeming okay. Then randomly, it will burst back into that noise.

Go to the Amp Mods and Repair board and read the sticky note at the top of the page on how to clean and retension the tube sockets then get back to us.

Might just be a badly seated or dirty tube pins.

Sounds like a bad tube to me. Fender ships their reissue amps with cheap tubes. I've had the exact same problem in the past.

I kind of doubt the sockets would need to be cleaned and/or retensioned if it's a new amp. I'm no expert though.

If I were you, I'd just take it to a tech. They can usually diagnose the issue fairly quickly.

Have Sweetwater send you new tubes. On them, of course.

Thank you for the replies.

Sweetwater agreed to send me a new replacement amp.

That was the good news. The bad news is it has problems right out of the box. Cuts in and out, reverb howls with feedback.

Thinking I should just send both back and forget the whole thing.

But before giving up, thought I would try troubleshooting a little seeing as I have 2 here. But the preamp tubes from amp 1 into amp 2, but the problem with amp 2 is the same.

Sweetwater tech thought the problem with amp 1 was the power tubes, and looking at them, one looks dim and the other has a lot of blue happening.

Was going to try putting the power tubes from amp 2 into amp 1 but want to be sure that's okay to try. The power tubes in amp 2 are rated 9 and the power tubes in amp 1 are rated 5.

Thanks.

I posted about this in the repairs section. I found replacing both of the 6V6 power tubes corrected a similar symptom.
