Bottlehead Seduction and tube rolling help


Hi all,

I just purchased a bottlehead seduction phono preamp. I think that the amp is fine but that I need to do some tube rolling before things start to work for me in my system. Currently, I find the tubes to be not very detailed or transparent. The current tubes are some kind of made in holland generic tube. I've also tried some russian 6922s. What tube would bring more detail and transparency.

thanks

Mofi, you cause me concern....and you critcize me for loving blue meters....uh huh..yep:)
An offbeat suggestion: Toshiba 6DJ8. A friend brought over his just-built Seduction and several of us volujnteered just about every 6922/6DJ8 in the book for comparison. He went home with a spare pair of Toshibas I happened to have. Their sound in this unit surprised the hell out of us :-)

I have one thing to add to what the others have said. I use my seduction as a tape pre for my R2R, and went through quite a few tubes trying to find the right sound. Well the seduction takes forever to break in, so you may want to wait until you have many, many, hours on it; then try some of the tubes suggested here. I still haven't finished trying tubes for mine, but I found a Tesla and a ECC 288 to be pretty good so far.
Thanks for the advice

This is a used unit and is broken in. I previously used the phono on an audible illusions 3a. This unit was touted as being in the same ballpark. Although the sound stage is good. The presentation is simple boring. I completely is lacking in dynamics and transparency. So I am looking for a tube that can emphasize these two aspects through out the spectrum.

thanks

A follow up question is ... have other found their seductions this way? I don't really want to buy - sell and audition many different tubes. What tube will get me there the fastest to avoid the process of rolling tubes for months and months.

thanks
Talk to Jim on tube asylum he is very pleasant and will get you where ever it is that you want to go. The only requirement is that you already have a preference for the type/style of sonic you want. He will tell you what the tube to use is and can generally provide it. He won't sell a tube he wouldn't use himself. When he says tested for noise and microphonics he is telling the truth, this is a critical aspect in order to save a fortune by running though a string of noisy tubes which in your application are useless.
I assure you most everyone that buys from him are pleased.
You didn't notice CV2943 a couple of times!
A side to Dopogue:
I bought some Marconi Citation 6SN7 GTB because the 6SN7 has the tone timbre in general that I vastly prefer I already have many of them and you can always find some worthy of a listen. Marconi in a GTB I presumed was Marconi Canada not Marconiphone or Osram. I was right what I didn't expect was that the Marconi Canada which was a brand under the rebrander umbrella of Rogers brands outsourced to Japan. I was a bit surprised but the boxes alone are priceless. The sound get this is better than merely decent it is fairly good. I am pretty sure it is a Matsushita product. A lot of Japanese tubes were made on Phillips machinery and the tubes seem to be good in general. Remember this is pre Honda and Toyota becoming well known high quality if boring cars. The last thing you wanted to see in the 60s was made in Japan. I will go out on a limb many already have and say as a rule the bad Made in Japan monicker doesn't apply to their tubes.
