SFL-1 was my 1st tube preamp and then slowly upgraded to Line 3. Actually SFL-1 and SFL-2 were pretty good compared to competition at the time. My biggest mistake was tube rolling and upgrading Line 3 and Power 3.
Line 3
uses 10 6922/e88cc and 2 6U8A so for the money I spent, could of bought a new preamp. I finally replaced the Sonic Frontiers with VAC and it's like going from Kia to Mercedes.
The plus side is gained tremendous amount of knowledge on tubes. :-)
