The SPF 15-2 is an external capacitor pack with 1.5 million micro Farads for the preamp/line stage and 660,000 micro Farads for power output stage.
For any component that has options to upgrade both the line stage and output stage, the SPF series allows you to upgrade via both jacks at the same time, while saving some space and money with a combined unit.
There are no controls and connection is simple, connect to the SP and FCF jacks with the integrated pigtail cable, and turn on your device. An external grounding tab on the chassis is mounted on the rear for any issues with grounding.
The center circle will glow a warm blue when fully charged, the multilayered faceplate has a glossy black exterior with a deep red acrylic behind showcasing the electrical symbol for capacitors.
