My KT 66's are 9 months old.........my Rt 66 sounds weak as compared with one I heard in a store 2 days ago. Not a lot of "pop" and tightness in the bottom end. I have gigged about 20 times with this amp and played on average 1 hr per day....using an airbrake.......cranked on setting 4.
I guess my question is whether this is enough to wear my Power tubes down? Maybe the bias is off as well..............any thoughts?
Using any attenuator to be able to crank and amp up will wear out tubes much faster. It is not the attenuator ... playing the amp at the same level without the attenuator will have wear be just as fast. This is primarily true of all class A/B grid biased amps such as the Route 66.
You are due to have the output tubes looked at and I would look at the phase inverter while I at it.
Not to mention (if you can afford it) to always have a spare set of power tubes around. Not only will you have backups in case one blows up, but you'll also have a set you know is new in case you think the current set is worn out. Put in the spares, see if you can tell the difference.
Also, using an attenuator (as I do too) will change your sound....especially the punchiness/percussivness. The more attenuation, the more it compresses and lacks punch. Did you use an attenuator in the store? If you didn't, that could make a BIG difference!! Mine is a different brand of attenuator, so I don't know what 'setting 4' is.

...........Nah ..........I do all my comparisons without the attenuator. As long as my 66 sounds like all those soundclips......thats how I like it. Definately gonna be replacing the power section.........Good luck with the gig gtrman3.......saw your post in the Rt 66 section. My fav for blues is my 335/Rt 66 comb........killer!

GuitarZ: Needed some noise to fill a break in a tune I'm recording. It was too quiet. Just happened to have some High Quality Dr Z Ghia noise to fill the void. "Heal Your Sound with Dr Z! It's not just a guitar tone prescription!"

GuitarZ: Must be great to be a skunk. Eating bird food about 10' from our sun room. I'm clapping and yelling. At best, it might have given me one "yea what?" look while continuing to dine. At one point, there were two skunks and two racoons.

easyed: Guitar Z, I encountered to ultimate garbage raiding combo once. We'd been having problems with the garbage cans being raided by raccoons for weeks. Late in the evening I heard rattling at the cans. I went out and found that he'd allied with a skunk. "OK"

GuitarZ: EasyEd - Someone at work topped us both. The inside of their car had been somewhat ransacked. They were blaming their son. They checked the video. It was a Bear! I'll stick with the racoons, skunks, foxes, and squirrels.

bigboki: In this age and time when everybody are struggling and especially S&Ms I am amazed to see that kind of ignorance. I am really sorry for your experience dear Dr Z but it is for the better. You don't want to do business with those kind of people anyway.
