Sounds like tubes to me. I would order a new set of matched power tubes and whatever preamp you need before spending money on shipping, unless they are local to you. Cracking and popping is almost always tubes and even if you don't use all the new ones it's always nice to have spares. Does it have a EF86 tube? Have you tried lightly tapping the tubes with the amp on and the retainers off. Use a pencil eraser and if it's a bad tube the cracking and popping should get worse when you lightly tap it.I bought an amp and cab that was Vince Gill's. I don't really care about that. It pops, and crackles...I just want them to go through it, fix what needs to fixed and retubed.
I've called and emailed several times... Nothing.
Am I missing something?
I noticed earlier today that their website was down for "maintenance" which could be "code."
Try friending Dan on facebook. he's on there a lot and seems happy to help out users.
What I was saying is they might be busy running their business and not immediately available to answer stupid questions. They obviously have other **** going on, man.Why do you guys do this? Are you trying to be a jerk, or you just can't help yourselves from suggesting at every turn that there is some drama developing?
'ooh, founder is wearing a red t-shirt today, perhaps it's a sign that they are going out of business...'
Maybe their website is really just down for maintenance, like they have had the courtesy of advising is the case?
