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!

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.
