Is anyone experiencing a lot of popping and crackling on the Nitro's gain channel? Even after warming it up?

do you mean warming up playing or warming up on standby?

Warming up on standby and also with the volume off after playing. It just crackles and pops like the cereal. If I remember correctly Scott told me that he was having some issues with the KT77's, but it doesn't seem to do it on the clean channel. I'm thinking if it was a pwer tube going south then it would crackle on the clean also. Could it be a preamp tube?

Sounds like power tubes. My Competition did this twice. Each time a tube failed fairly soon after.
Seems that, much like the movie "Lost Boys", all tubes die differently. Some go silenty, some scream, some explode.

I actually experienced a little of this and I switched cables.The cable I was using was kinda old and I thought it might have been going south.I switched and havent had any problems.Another thing is that it might be your guitars pickups.Have you tried a different guitar? Appliances or TV`s on in the room or house?Anyway,just some things to think about. |

It does it with nothing plugged in the front. It is in a sound proofed studio with nothing to cause interfence. I'm thinking tubes, but which ones? I have a sneaking suspicion that it is going to be one of the kt77's like Scott mentioned. They are only a little over a month old. Sux.

I dunno man, if it's only happening on the gain channel, I would suspect a preamp tube more than a power tube. Have you tried swapping the pre tubes associated with the channels to see if it changes anything?

This happened on my QR and it was the pre-amp tubes. New tubes, crackling gone.

Im having the same problem. I swapped ALL preamp tubes. Not the problem. I am also running JJ KT77's which are about a year old. Going to put EL34's back in.

i've found KT77s to sometime have a problem with random popping sounds. but it goes away after sometime.

also check to make sure the tubes are sitting properly in the tube sockets. sometimes if a tube isn't sitting properly or has some wiggle room it can cause popping. maybe retention the socket connectors?

I'm thinking pre amp tube or tubes. I have some ecc81s I can swap in to see if it fixes it.

yeah it sounds like preamp tubes if it's only doing it on the gain channel
