I'm going to be getting a therapy this weekend and ive been reading a little bit on the tubes that it takes. Am I correct when saying that I can use 6L6, 6V6, EL34, and KT77 power tubes in this amp? I want to make sure before I try to experiment with them that I won't screw the amp up. And also if true which power tubes out if those 4 do you guys most like? And which woukd be the best tube for blues rock?

KT77's or 6V6's with an alnico speaker are the bomb diggity for clean to semi dirty tones.
When I'm jamming around the house, I can toss the 6V6's in there and get some good drive going with a 96dB speaker without aggravating the neighbors. The KT77's give me a little more cut and less squish at gig volume.
6L6's are great, too, and I really like them when I can crank the amp. I just wasn't a fan of the EL34's in there. Lots of options. Try a 5751 in V1, too!
I agree on the 5751 in v1 option, defiantly gets you some more clean headroom and sounds good. I tried some 6v6s in mine also and liked the result. But from the basement to playing out I do heavily prefer a 12xax7 in v1 and the JJ 6L6 power tubes. I use two Celestion Gold 10s with mine, an amazing amp that is going no where!

I told Him a Powerful 35! watts , It was Really Singing!!! , used w an Original 1x12 EVM12L MY FAV W THE AMP BY THE WAY

Think I have a pair of JJ KT77's downstairs that were briefly in my SRZ-65 (until I found a "good" pair of EL34's for that amp). If I may say so, outside of the BS&T, they're available if somebody wants to try them.
Own or have owned: M12, Carmen Ghia, Rx JS, MAZ 18 Jr NR, Monza, Z-28, Route 66, Therapy, DB4, Remedy, Prescription, EZG-50, SRZ-65 LE, & Delta 88 Z-Drive | Brake Lite SA & Air Brake
I just put a pair of JJ KT77's in my Therapy ... wow. As advertised, it provided more clean headroom than the 6L6. But that headroom has, well, "guts." It makes a great clean, gutty base for pedals, and sounded great with my '81 Strat. Real "oomph."
Ran the MV at 3-6, vol at 9'ish, bass at 9, mids at 3-5, and treble at 3-4. I love 6L6 tubes, but this may the ticket for the Therapy because it pairs with a stock Z28 through a Z 2x10 open back that I have set to provide a lot of gritty overdrive (not quiet the 3-3-3, more like 3-12-3).
I also have a 5U4 rectifier i'm going to pop in tomorrow just to see how that sag feels -- I think I'll end up staying with the stock 5AR4. BTW, playing through a vertical slant 2x12 with V30/H30 top/bottom.
Jaguarguy (Mike): Hey Gary - Joe Walsh used a G12 65 in his Galaxie and it sounds great!

GuitarZ: So, I cranked up the privacy protection on my browsers, facebook, etc. I have to say I miss the music ads and such. I really don't need ads for watches and other random stuff. Maybe the internet knowing me isn't such a bad thing.

Joey Beverages: hayesgary307 try a Z 210 or Z 410 with Galaxie ... also, yes the G1265 is most tasty and excellent

GuitarZ: Reminds me of buying my Honda. When they tried to sell me the maintenance package, I said "Is your car not reliable?" Long story short my wife teamed up with the sales lady to buy the maint package. Never again!
