Thanks a ton for the help guys. I spoke with Chad before I got on the forum and he suggested that it was probably a tube issue. I just wasn't able to isolate which one is acting up. I unplug my amp everytime I am done playing and that hasnt fixed anything, at least up to this point. I need to just bite the bullet and order new tubes. The crackling drives me insane! I have been looking at Tung-Sols. What do you guys recommend? I like the vintage RCA's but I am looking for somthing a little more affordable. Thanks again for the advice.
I would order same tubes TR uses and get your amp right first.  Also, bias to what Chad recommends.  For TR SP22, Chad had me set bias at .44 and informed me to check it every month or so, which I never would of thought to do, as I'm just a plug n' noodle guy, but will now.
