Howdy,
I bought a Rt. 66 new in Oct. 2006. It sounds great!! Yesterday I noticed a little crackle which I presume to be a tube going bad. The amp had been on for several hours and when I put it on standby and came back to it 20 minutes later the crackle was gone. It's not loud enough to be a huge problem at a gig but I wouldn't want to record it as it is now.
Do I replace all the tubes or attempt to find the bad apple? If I bring it to my amp guy does that void my warranty? Any suggestions appreciated.
BTW, I didn't get any warranty card or documentation from the dealer, although the amp is new. Is that normal?
Thanks,
John

Someone with authority here should speak up soon, but I think you should be able to take it back to where you purchased it.....especially since you purchased it new.
From what you're saying, it sounds like your ef86 tube to me.
Is it a crackle when your playing, or when your not, or both?

Its probably the tube in V1 replace it and see what happens. Its a good idea to keep spare tubes on hand anyway as they are usually the place to look when your amp starts to go downhill. You can save yourself a lot of time by just changing out that one tube first before hauling the amp back to where you got it and having to wait for them or the good Doc to figure out the problem. If it is the tube in V1 you can fix this whole problem in under 4 minutes :-)

Thanks for the speedy reply. I'll have to check it again today but I think it was only happening while I was playing, or at least was much more noticeable.

John do your self a favor, re seat each tube one at a time, then tighten the four bolts holding the chassis to the cab.
A crackle is a loose connection for the most part, don't throw out the baby with the bath water, could be as simple as your power cord loose.
On the other hand Snap and Pop , well those two wild dudes, makes for a great breakfast cereal

Well, the problem hasn't resurfaced. Last time it only happened after the amp had been on for a long time so maybe the heat loosened something? Anyway, I've got another long session on Monday so the conditions will be repeated and I'll have a chance to check it out again.
