What tubes sound the best in your SE84CKC?
02/18/14 at 00:42:36
 
Just got my new Zen and i am very happy with the stock sound driving my vintage Altec Lansing Laguna's. Surprised at the loudness level for just the two watts :)

For a little better sound i have replaced the stock rectifier with a NOS Mullard GZ-32 and the input tube with NOS Amperex 7308, but changing the output tubes to some other EL-84's.the sound is worse. Even with
some really good vintage tubes, i have found the sound to the best with
the stock Russian Rockets. With the EL-84's the volume level seems a lot lower and there a muddy sound with a tad of distortion. YUCK!!

What are others using?

I know you're aware that the sound will change a lot as your new amp
settles in. This can take some time, so while it's tempting to start tube swapping straightaway, what sounds " off " today may be much more
involving down the road.

Doorman i appreciate the fast reply and i agree the amp will sound different in the future, but tell me what tubes you are using like i asked.

I have 3 other tube amps including a SE34I.2, which i switched out the
stock tubes the first day i got it for vintage tubes and now it's 6 years later and the vintage tubes still sound WAY better than the originals.

The CKC pushed the limits of the 6922 type input tube so I doubt that the 7308 would do better than the 6N1P-EV

I agree - I was just mentioning that I went back to the tubes Steve put in my old Zen after it's recent tune-up.

tesla 7dj8seems as good as 6n1p. Any thoughts on the large labeled 6p15ev as opposed to the small label of the same tube????

60's Phillips  SQ E88CC  60's,  Phillips 5R4GYS best combo for me so far. I don't roll the 6P15P supplied with the Zen.
