I tried doing a search on "6L6" and "6L6 Tubes" but I get an error that 6L6 is not enough characters and need at least 4 characters to do a search. Strange!
Anyway, I did find a few threads where guys asked if 6L6's can be used in the Route 66 and heard things like it was designed for KT66s, different filament current,very pricy ouput transformer that is implemented in ultra-linear fashion. etc. but nobody has answered definitively whether or not they can be used and if so, what is the expected result? Anyone?

The 6L6 can be used with no issues at all .... just bias properly as they typically have about 10mA less output for a mid range tube than a mid range KT66.
Marshall shipped a lot of Bluesbreaker amps with 6L6 / 5881 .... and McIntosh had some cool amps with 6L6s that folks used KT66s in across the pond.
The tubes are interchangable ... just rebias.

Hmm ok so basically the 6L6s would have a bit less Oomph then?

Just my personal opinion:
The Doc and Myles are right, you can use a 6L6 in the Route 66. However, the Route 66, unlike the Marshalls, is an ultralinear amp, and I don't think that 6L6's sound as good as a "real" KT66 in that circuit.

Well, as for putting 6L6's in a Route 66, my mother said if I had nothing nice to say, don't say anything at all...

Even in an amp like a JTM-45 Marshall I feel a lot is given away if the amp does not have KT66s as original designed.

Not the same at all and in fact they are not really 5881s. Today's 5881WXT sovtek is really just a 6L6. They are really the same tube with the same spec, 5881 used to be the industrial designation for a 6L6. Now in the 50s and 60s Tung Sol made some amazing 5881s that fetch a premium today. But ..... a 5881 is NOT a KT66 anymore than a 6L6 is. KT means Kinkless tetrode ... it is completely different design. A few years back Marshall reissued the classic Bluesbreaker combo. At first it was about 10 3/4" deep and you could fit KT66s in the amp. Then the depth was reduced to 9 3/4" or so and KT66s would no longer even fit. On top of that, the reduced speaker cab volume lost low end. Now they have gone back to the original dimensions when they offer these but still do not ship with KT66s. A KT66 is larger than a 6550 or KT88 physically.

Very interesting! So would a KT66 fit into the newer JTM-45? By the way, does Doc make anything similar to an original JMP 50 for the late 60s or anything in the works?

KT66s always fit into JTM-45's .... it was the Bluesbreaker reissue combo that had the problem. If you like Marshall amps go try an SRZ-65 and be done looking for the classic Marshall sound. On my GAB website there are some clips and a lot of info when Carl Verheyen looked into replacing his Plexi Marshall 1987 as it was getting too valuable for the road. He found the SRZ could do all his non-master plexi could do but then also do much more. If you want a Marshall that does what the great ones that were the creme of the crop did then go play with an SRZ-65.

Ah! That is exactly the info I wanted! Thanks Myles! Aren't those discontinued though?

Awesome! That I think is exactly what I'm looking for to run my 66 in stereo with! I plan t do a Jimi/Trower Tribute band. I just wish I could disguise them to make them look like Marshalls for the Tribute act look but that would be taking away the Z cool factor like Brad Paisley has established. ;-) I heard Jimi page used to hide a little Supro inside his Marshall stack and mic it up for his big stage sound though not sure how true that is. The 66 nails the Jimi early Wind Cries Mary, Hey Joe tones with the SRZ-65 a'la Trower stereo setup I should be set! I know he uses a JCM 800 and a JMP 100 Plexi in the U.S. and 2 JCM 900s in Europe for the bigger sound though my JCM 900 doesn't come close to the 66. I was thinking of trying to find a 67-69 Plexi JMP 50 after reading the recent article in Vintage Guuitar magazine how that's the holy grail of rock tone but aside from costing a mint, I would be afraid it would crap out on me gigging and if you recap it would probably change the original sond anyway I would think. I just think the 66 is the smoothest, richest sounding amp I've ever heard and I was using JJ KT66s so I can't wait to hear how the Shuguangs sound after Brent gave me the heads up on them being used in the new units. Anywhere I can hear a couple clips of the SRZ-65?

Anywhere I can hear a couple clips of the SRZ-65? Recapping a plexi 50 will alter nothing and caps over 10 years old in these amps have probably been replaced. And ... if the amp was not played and just stored the caps die even more quickly. Sound clips - Go buy Take One Step from here - www.carlverheyen.com/store.htmMaybe there are clips in the SRZ-65 area .... Or just listen to any of the greatest Marshall 2204 tones on record and realize that the SRZ will do them even nicer. Or .... listen to the song Slang Justice on the DVD Rumor Mill at the 5:00 mark - the icon example of a Strat / Marshall rock tone IMHO.
