Herron VTSP-360 Line Preamp
Herron VTSP-360 at a Glance...The Herron Audio VTSP-360 uses four type 6922, or 6DJ8, or E88CC, or 7308 dual triode vacuum tubes.
The VTSP-360 has a proprietary one-of-a-kind tube bias servo circuit that optimizes the performance of many different tube configurations that are equivalent to the 6DJ8 type dual triode vacuum tubes.
Totally unique circuitry configuration and layout that produces high end performance from the tubes and extends tube life.
