Tubes for Musical Design SP-2B?


Need advise on replacment tubes for my pre-amp. Anyone with experience with this unit and tubes in general, your comments are welcome. I have an other pre-amp, but would like to see how good this one can sound. Thanks.

I just replaced some Sovtek 6922 with Telsa.I prefer the Telsa.You could do worse than the Sovtek though.They are not bad and for the price you cant go wrong.If you want to spend large go for the Siemens E188cc 7308.
6DJ8 tubes. Go to Musicaldesign.com for info. They are cheaper to buy from than other sources. You need a MATCHED pair!! Sovetek work well.
