I am having some trouble with my Rebel 30 combo.
Here's the problem: When I turn the amp on it sounds great and works fine for a while, however, after 3 to 10 minutes of playing there is a deep pop and then a loud continuous buzz. The buzz resembles the sound of an unplugged guitar cable but louder and deeper or lower in frequency. The buzz overpowers the signal to where if I continue playing my guitar is indistinguishable. There is, however, a very distorted (the choppy bad kind) low frequency response when i play my guitar while the amp is in "buzz mode".
If I turn off my amp and let it cool down it will sound fine again for 3-10 minutes and the pop-buzz thing happens again. This happens on both channels. The buzz continues when there is no guitar or guitar cable plugged into the amp. It also continues through the record line out so it shouldn't be a speaker problem. Lastly, I discovered that when I turn off the amp without putting it on standby while it is buzzing, the amp pops and goes back to normal before the signal fades as the amp powers down. (I know that I should never do this, I don't have a habit of doing this, I discovered it on accident.) The amp is eight months old.
The fuses seem good and the tubes seem fine and the speaker seems fine. I feel like the is only a problem after the amp heats up after playing for a bit which leads me to believe that there is an issue with the circuitry or soldering.
Is there anything else I can do to troubleshoot apart from buying new tubes? (These tubes have been used only moderately over the past eight months and my amp's symptoms seem rather extreme for any dying tube I've ever heard of.)
Any other troubleshooting ideas or should I pay an arm and a leg to ship it out to Egnater under the warranty?
Anyone else have these kinds of issues?
Peace
