After my disastrous experiments with TungSol, I'm definitely waiting for someone else to try them first.
Any "official" reports from Myles or Doc regarding these tubes yet?

iggs- my new 66 came with JJ KT66 installed. They sound GREAT!! I could really tell a difference from the GT 66's that were in a loaner the dealer gave me until mine came in. There are a couple of threads here the JJ's are discussed. I'm sure Myles has some good info. MHO I like 'em !!

Got my JJ KT66's today but have not installed them yet . The 1st thing I noticed was the weight of them , the glass is as heavy as that used on a mason jar !! If that is any indication of the construction they are one rugged tube !! ;D Hope to test drive em in a day or 2 .

I am eagerly awaiting a tone report on the new JJ KT-66s. I believe Myles indicated they don't trace like a traditional KT-66, but they have higher output. I hope it's not true because the tube amp community certainly could benefit by a wider choice in KT-66s. What KT-66 is Marshall using in the new Vintage Modern amp?

I believe the new Marshall has Groove tubes installed.

Go Ahead Bro....pull the pin OK ... so I did ... ;D Got the tubes on Monday and installed them yesterday. They were matched within 2 mA. First impression: - very quiet compared to Shuguang and Saratov ones (that I have), both of those gave a noticeable low-level hum even though the pairs were matched within 5 mA. The JJ's were dead quiet with Route 66 cranked to max. Just as a side note, I have two pairs of Shuguang and two pairs of Saratov, one pair of each are from Groove Tubes. The other pairs are from Tube Depot and Tubestore. - they are the brightest I tried so far and crunch quite nice when pushed. They crunch (distort) the least compared to the other pairs I have, both with my SC Strat and my HB Music Man. I biased the amp so one tube was at around 35 mA and the other one around 37mA. - It's hard to judge because by the time I switch the tubes, I've lost the sound image in my head but IMHO, the Shuguang sound a bit richer and fuller then the JJ, which sound just a bit thin ... I like Saratov the least and will leave JJ in the amp for a while and see how it goes. Did not have a chance to crank my pedals through the amp yet, will report my findings once I do.

I've got a pair of the old Groove Tube KT66s from they first put them out 10 or so years ago. Does anyone know any pros or cons about them?

If that is any indication of the construction they are one rugged tube !! ;D Hope to test drive em in a day or 2 . First off .... the sonic quality of the JJ is going to be personal preference. It is more like a hot rod 6L6 than a kinkless tetrode from the GEC design. That is not a good thing or bad thing. It is a taste thing. Bottom line is that it is great having another option from a maker of great stuff. On the weight ... and the glass bottle. This is a bit of the reason my wife says I am a vast store house of useless information.... The sand used to make the glass where the JJ tube factory is located is very high in lead content. It is so high in lead content (don't worry, this is not harmful) ... that it actually meets the standards to classify the glass bottle as fine leaded crystal. So .... when you finally use up the tubes, get somebody with one of those cutters that takes necks off beer bottles to make glass slides and have them cut off the base so you can get the innards out. Now you have a gift for the wife or girlfriend ... a little crystal vase! By the way ... the EL34 and E34L from JJ fit into the current VW Bug with that little spot to hold a flower vase on the dash! Bottom line on the JJ KT66 .... it tests good, it handles voltages far in execess of what these amps develop, it stands up to torture tests at 150% of design rating (such as running the tube for 12 hours at 45 watts output), is resistant of physical microphonics and probably will travel nicely in hard tour service. In the end your own choice will be a matter of tonal preference.

I cranked the amp today with JJ KT66 and my pedalboard with some dirt in front. Diamond Fireburst, SubDecay Blackstar, Cusack Screamer Fuzz, Retroman NüFuzz.
I like the JJs way more with heavy dist and OD sounds then the Chinese and Russian ones. Much tighter sound when pushed with dirt and xtra gain up front. I still think I like the other ones better for clean or no pedal sound but with med-high gain pedals in front I think JJs work much better.
I just find them still a bit bright to my liking (when compared to GT KT66C at the same setting) but turning down the Treble seems to cure it. Maybe I'll bias them differently and see if that makes a difference as well.

It seems like you are saying that the JJs don't have the same "milkshake thick" mids that the Chinese and Russian tubes have. Is this a fair statement? BTW what speakers and cab are you running your Route 66 through?

BTW what speakers and cab are you running your Route 66 through? Thanks. Yeah, I'd say it's a fair statement ... the "milkshake thick tone" is definitely there with Chinese and Russian tubes (more so with the Russian ones, they are darker and thicker sounding). With JJs it still sounds great but different. I use VHT 4x12 slanted with P50E Eminence speakers ... loud, efficient and tight.

Quick update:
Put the GT KT66C (Shuguang Chinese) back into my Route 66 today (I'm a constant tweaker ... what can I say) and I do like them better then JJ's. The JJ do sound tighter and seem to favor high-gain pedals a bit more probably due to being tighter and with a touch more headroom, but overall I think that Chinese ones sound richer with nicer low-mids and overall bigger sound.
