Many still love the sleek lower profile look of the Classic Nautilus and as such we allow you to order your Nautilus with the original metal work style.
The Nautilus brings the dual-mono layout onto a single chassis. We started with our most versatile circuit, the Mogwai, and went about creating two separate amps that share a single chassis. 2 Power Transformers, Separate Power Supplies, Chokes, and input transformers. The amps are built with separate turret boards, with the shared component being the input tube, volume control, and outputs. We were unconstrainted with parts selection and layout and chose the most robust power transformer and widest/least distortion output transformers we could find.
The Nautilus’ hand build nature and part selection necessitated a robust hand fabricated chassis. We partnered with our existing CNC metal fab house to build a 12 gauge steel chassis with bracing that could support the 44lbs of transformers without a hint of strain. In total, the Nautilus is 68lbs before packing. We additionally choose to cover all the transformers and business end of the amp with a gorgeous chrome cover.
