The Model T Mini – Sunn PreAmp is a compact version of the Sunn Model T amp, designed for stoner rock enthusiasts. It offers the same growling tone as its larger counterpart but in a smaller 1590B enclosure.This preamp can be configured as a twin-channel preamp, with both channels wired in parallel. Alternatively, you can add a toggle switch to switch between Normal, Both, and Brite modes, or simply between Normal and Brite with a two-way switch.If you’re comfortable working with surface mount technology (SMT) components, you can opt for surface mount FETs to save some money. However, through-hole components are also an option. Regardless of your choice, the FETs can be easily biased to achieve optimal performance using the trimmers.The preamp features controls for Bass, Mid, and Treble, as well as separate level controls for each channel (Brite and Normal) and a Master volume control. The pots and toggle switch are conveniently mounted on the board, ensuring a tidy build and secure mounting in the enclosure. Please note that the pots have round shafts, so you’ll need knobs that are set-screw fitting. We recommend using 1900H knobs, as the pot spacing is only 17.5mm.
