New Rebel 30 Head Died in 5 minutes :(

[joto]

I received the amp ( Rebel 30 and matching 1x12 Cab on Thursday and dropped it off at my drummers house. Last night went to play, set up the amp , correct ohms etc. Plug in played about five minutes, started to crackle when adjusting the volume, and it died. No smell tubes light up, all lights on , no sound. Bummer no Jam. I emailed Nate at Egnater and the Music store i got it from but both are closed till monday. I heard things about faulty tubes with the combos I hope this is the issue . On the bright side it sounded great for those five minutes .

My bet is bad power tube which may have taken the B+ fuse. They will still light up though. Nate or John will take care of you.

Really not funny...I would check the tubes and fuses.I always have spare tubes around..Sorry for you.

 

[joto]

Thanks i am not worried. And i normally would have extra tubes for a gig but it was just a Jam and i just unpacked the amp and it was the last thing i thought would happen .

tubes can be dead even if everything lights up

Most likely a tube issue as stated above, which probably blew a fuse. You could try moving your tube blend knob all the way to the right or left, if still no sound, then most likely its a blown fuse as well. Heard there have been lots of issues with the tubes in the 30. I have the head, and so far so good.

This conversation makes me wonder about a related topic. What if a power tube goes bad on the Rebel 30--let's say it's one of the 6v6s--can you adjust the tube mix to EL84 and keep playing? Would it completely stop working, or do some damage?

Thanks!

I believe you could adjust the tube mix knob all the way to the other side and still play, and this is in fact an indicator that your set of tubes of a specific kind went bad. But if you blow a fuse, then most likely you will get no sound period

This is a head as well and brand new

Same thing happened to me after the amp was fairly new. I'll bet money it's a bad tube + blown fuse as everyone has said.

Definitely pick up extra fuses (I bought like 20 on eBay for $5). I swapped the tubes out for better quality ones and I've been rockin' free and clear ever since

Don't let it get you down - it's a fantastic amp! Just be glad it didn't happen at a gig!

Oh, and just for the record, you can turn the tube mix knob to one side or the other and keep playing (as long as your fuse didn't blow). That's the way to check which tube or set of tubes has gone bad. And, even if you don't have replacements for one side or the other, you can take them out and play on the other side, which is another cool feature of the amp.

Yeah, luckily I've only had it happen to me at practice. But I just replaced the fuse and found out one of my 6V6s was bad. Pulled them out and played on the EL84 side with no problems (other than slightly less headroom).

Which tubes did you swap in?

Spoke to Nate at Egnater today. He had me run s test by plugging in a guitar to the return of the amp to see if there was any sound as he though it might be a V1 issue. Still no sound. Since the lights are still on he says the fuse probably did not blow. I did look at the fuse and it appeared that there was no filament but i am not sure if there is supposed to be one and all the lights work.

I got JJ 6V6s, and some NOS GE EL84 tubes from an amp builder/tech friend of mine. Both sound great to me!

Hmm...when I blew a fuse, the light would come on for me. And no filament to me sounds like a blown fuse. I would definitely start there. If the fuse is blown, you're not going to get any sound from the amp as far as I know.

Replace the fuse, then take out the pair of 6V6s (or EL84s...doesn't matter which set you do first). Turn the tube mix knob all the way to whichever side of tubes you've kept in, then fire the amp up. If it doesn't work, turn it off, check the fuse (it may have blown again...replace it if it did), then repeat the process with the other set of tubes. If you still don't get any sound, then I'm not sure what to tell ya, but I think this should hopefully diganose your problem as a blown tube.
