Model T - Sunn PreAmp
Stoner heaven. Sunn Model T amp growl in a relatively diminiutive 1590BB
Configure it as a Twin channel pre-amp hardwired for both channels at once in parallel, or add a toggle switch to go from Normal > Both > Brite (3 way switch) or simply between Normal > Brite (2 way switch).
If you're comfortable working with fiddly SMT components you can save a few quid and go for surface mount FETs. Through hole or SMT, your fets can be biased to perfection with the trimmers.
Controls for Bass, Mid and Treble, as well as level controls for each channel (Brite and Normal) and a Master volume. After some experimentation we're offering the bass pot as original linear or much better (in our opinion) log.
Board mounted pots and toggle switch for a nice, neat build and secure mounting in the enclosure. The pots have round shafts, so you'll need knobs that are set-screw fitting.
Supplied with Lumberg jacks for better clearance over the mounted circuit if you go for top-mounted jacks. Neutrik if you go for side jacks.
If you want the PCB without parts there's a link for that at the bottom of the page.
Partial kit: PCBs, all board-mounted components depending on selected options (not footswitches), pots.
Full kit: As above, plus footswitch and appropriate daughterboard/components for your selected bypass type (see Downloads section for details of those), jack sockets, DC socket, battery snap, hook-up wire, LED.
Enclosure (pre-drilled) is available as an option with full kits, and will not take a battery. Knobs are not included.
Builds are only available with full kits including enclosure and vertical-mount pots, and only with through-hole FETs. Please choose appropriate knobs.
