This is an advnaced version of the Sonic Frontiers SFL-1 preamp sold through the Assemblage line of components.
Highly capable preamp that has been in my system for a long time now.
Uses a single E88CC/6922. Can be configured to run a 12AT7 by moving a couple of jumpers.
It is in flawless condition.
Sovtek 6922 included with the preamp.
650 plus shipping CONUS. Will come with the manual.
