Fav Tube/Best tube


E80CC my all time fav, any brand, all sound nearly identical (pinched waist, getter stuff = snakeoil)
Tungsten, Siemes, Philips = same tube.
some have rhodium pins, ebay seller claims *sought after = superior to brass pins*,,,but these rhodium pins, do not have the copper posts, which i perfer. I will have to roll the E80’s , so far I perfer vavlo by a *hair*, but can not say for sure, as all sound nearly identical, at least to my poor hearing( I failed a hearing test at Valero Refinery some yrs back , but only in testing the highest FQ’s).
Next fav tube
is Tele 12AX7, Siemens are very close,,at least as far as i can tell, have not made a further compare on that as yet.
Next and last is the power drivers.
For that I’ll have to go with the KT150’s, which i’ve not heard, but am sure will love that tube.
When I rolled the 90’s to 88’s, i might have perfered the 88’s ,,,both sound very close,,,,sorry i should have made more shootouts on those 2 , before i sold off the 90’s.
Considering nearly all amps come with stock 88’s, that pretty much confirms the 88’s is the all around best tube for most amps, |
BUt if you have power to spare in your trans, as my Defy does (2 side trans run cold, mid trans runs slightly warm,,and thats running super low super high demanding 87 db speakers!!! Testimony to jadis' trans, built like german tanks, yet sing like ,,,,, Heavenly Angels) the 150’s is the best option as a long term investment.

So thats my 3
1) E80(far superior to the wimpy 12AU7’s, if the e80 did not exist, the 12AU7 is a excellent tube <<<tongue in cheek>>>)
2)Tele12AX7
3),KT150’s.
and yours?
and go ahead and dunk all snakeoil you’ve heard over the years about certain aspects of a tube, such as *Holy Grails*

I mean RT (La Radiotechnique)that Became later RTC (Radio Technique Compelec).
Tubes are engraved FRS, made in the cities of « Suresnes« and « Joué les Tours » (France)They made RT and RTC tubes for French military, labs, industry, national rail (transport by train) and so on.
Since 1947 they were part of the Philips that sent parts of their machinery group and made tubes under the Miniwatt Dario name but also their own tubes. They also exported tubes under Impex and sometimes Impex Dario in Great Britain.How is it possible RTC and Philips sounded different ? I don’t know.
I have the 12 AU7 CIFTE in my amps and they are wonderful tubes. I compared them to many incl some of the best and they are as good as any.Also the RT 12AU7 WA are very close to the CIFTE 12AU7 WA and WAH.
Maybe you can find some RT WA or WAH. I have both and they are so closed that you can prefer one or the other. Often it depends also of the other tubes around. Tubes in an amp or in amp and pre, if they are both with tubes, are an assembly like yours whole system. The way you marry the tubes to manage the final sound you like is very important.
This is the same thing you do when you marry your speakers to the rest of your system and your system to the room.
