HI TO ALL FRIENDS HERE.

im wanna replace my old tubes and my currently tubes are:
electronic tube 6cs7 made in usa(pre-tubes) ,sylvania 6cj3(stabilizer tube), goldlion kt77 genalex made in russia(power tubes).
i must say i read all the posts here and i dont understand few things.1. the kt 120 tubes is the power or the pre tubes ?
i guess the power or im wrong ?
2.Reflector 6n3ce tubes is replacement to the 6l6gc or el34 ?
i like to know if i order the original tubes from leben company its mean the leben sounds is not better then all the tubes you suggest here?
thats all please im so confused about this models of tubes and i like to do smart and good purchase please help me
thanks alot and sorry about my english.

Hi Bolero,
The Reflector 6n3ce is a 6L6, a really long lasting, tough as nails tube, yet it sounds wonderful in your model Leben. If you would read Jeff Days review, as I have suggested, it would clear up your confusion. A s I previously explained, Jim McShane (a highly knowledgeable and trusted tube seller) sells them for approximately $65.00 a Quad, about 260 new Israeli Sheckels. READ: Jeff Day (Google him).

ok . im understanding now Reflector 6n3ce= 6L6.
bout few things more what about the power tubes ?
and stabilizer tube?
what to choose im already have now KT77 GOLDLION GENALEX tubes and Sylvania 6cj3 stabilizer tubes what recommend?

and why is better to prefer them on what Leben suggest that is keep the leben sounds ??

After more than 2 weeks i must say these tubes shine. and when i put on the reflector After getting sued to this the music seems to have gotten Duller (relatively speaking as i used to love this before)
I would wholeheartedly recommend them over the reflector (next best) and the SED (after both of the former...not having heard other 6l6's)
The Bass is so much more articulate and the double bass is to Die for (Kings of bass- Gary karr, Ray brown - producers cut) the lower end harmonics have never been more clearer...and with no loss of midrange purity. I played the Chesky's ultimate demonstration disk yesterday night and was in raptures during Ms Pidgeons voice...which is not my usual favourite.
Bolero, the dumper tube has no sonic impact (or so i believe) as it only regulates the current initially so as to preserve the life of the power tubes. so would not have any impact
I really dont know enough about the KT77..they would be good no doubt.

Regarding Leben sound, from my personal view, the tonal shifts will occur with any tube .. but you will not lose the slam and the power expected out of an SS which the leben brings about along with the micro dynamics and the tube like immediacy & fluidity across the full range....and thats a pretty unique combination (of course which would mean compromises with what an SET lover would expect)

@Kujocku - 6L6GC/6P3S-E/EL34s

All - drop the kt120s in. You won't be disappointed. Better everything but your cover comes off.

Popin the top never sounded soooo goood
