New tubes for SFL-1 / SFS40


Hello,
I'm thinking of replacing some tubes for both my amp / preamp. Currently, the system doesn't sound "tubey."
I heard the nature of SFL-1 isn't very tubey...but I am
hoping that replacing some tubes on both pre/poweramp will
give me the "tubey" sound that I'm looking for.
Please give me some suggestions on the tubes.

Thank you very much!

Thank you for all your responses.
To clarify, I have SFL-1, not Line 1.

Dekay, do you know where I can purchase EI Elite 6dj8?
I am thinking of trying them out.

Many of you suggested that I change my system. I think you are right but before I do that, I like to try some new tubes. I am purchasing a ZERO Autoformer for my system...I am hoping that will make my system sound more "warmth".

Thanks again.

Hi Sean:

This is the only source that I have, though there should be others.

http://www.tube-shop.com/index.asp

Prices are in BPS, so maybe 1.5/$US (haven't checked lately). Includes VAT and shipping is cheap.

I will probably try them eventually along with the 12ax7/12at7's.
Looked it up and now understand the 6DJ8s are for the amp, not the pre. My mistake.

A synopsis of the characteristics of a variety of 6DJ8 tubes is located on the Audio Asylum at http://www.audioasylum.com/audio/scripts/d.pl?audio/faq/joes-tubes.html#6DJ8. Maybe that will help narrow down what tube will do the trick.
Hi Sean,
I know that you wanted to change tubes to get the 'tube' sound, but you may also get a lot of that type of sound by changing the coupling caps. Their are 2 pairs of caps to consider in the SFL-1, and a quad set in the SFS-40. Paper and oil caps may be the ticket for you.
Have fun!
Wow...this is getting interesting.

Dekay & Fpeel, thanks for the link.

Dtails, where can I find more information on caps? DIY? I'll do some research on AA. Thanks alot. This is fun.
