serious buzz/hum egnater rebel 20

[ratchet1021]

i have a serious buzz/hum in my rebel 20 head. i bought the head in the fall/winter of 2011 and instantly fell in love with it. this thing is a tone monster! but it has recently developed this nasty buzz/hum. impossible to play over this noise. it's extremely loud and super frustrating. i've attempted to isolate the problem, but i haven't disassembled the amp in any way. here's what i've tried so far: 1. i make my own cables and thought maybe this was the issue so i've tried different cables. made no difference. 2. eliminated my effects by plugging guitar straight into amp. no difference. 3. plugged nothing into amp. made no difference. 4. i've used a different power strip. 5. tried different wall outlets. 6. used a different power chord. 7. i can turn evey knob and flip every switch (besides the power and standby switches) and nothing has any effect on the noise. 8. i've plugged a different head into my egnater 2x12 cab and i have no noise. so i know it's not my cab. 9. i emailed eganter several months ago and got zero response back. this was rather disappointing too. anybody out there having the same issue?

Sorry,no issue with my Rebel20 (+3 years).Did you look at the preamp tubes ?I would check the tubes and would swap the preamp tubes one after the other with a sure one first.Good luck !

Could be a power tube since none of the knobs affect the buzz but that is just speculation. May need to get it serviced?
So, are you saying it has been broken for three months? You emailed once and didn't get a response so you just live with it? Do you recall where you sent the email to?
Do email Nate (nate@egnateramps.com) or phone him directly at 1-877-EGNATER. I apologize if you didn't get a response from your email but there is no reason you must live with the problem forever. I'm sure Nate will be happy to take care of you.

it's been "broken" for quite some time. i wouldn't call it broke, i believe it's fixable. originally the issue was very intermittent. you never new when it was going to act up. it could work fine for days or weeks with zero issue. then it started getting worse. more frequent. to the point within 5-10 minutes of play time is all you had. i didn't exactly live with it, no. i have another head to play through instead. figured i'd get it fixed sooner or later. i'm miles and hours away from where i bought it or probly any where to service the amp (i'm kinda in the middle of no where). time for a road trip just wasn't adding up. i used the contact service on the egnater website. i figure those guys get pounded with stuff all day. i wondered if it was maybe a tube. but i didn't want to disassemble the amp in any way. i'm not sure what kind of warranty would be on this, but i wasn't going to void it.
