FatStack™ transformers are custom-designed Mercury Magnetics transformers that have extra steel laminations. In an output transformer this extra iron extends the bass frequency response. In the power transformer it can minimize tone drift giving your amp more stability and headroom.
Our SuperStack™ transformers are similar but are built higher to accommodate smaller mounting footprints.
