The SB-1 provides an easy Power Scale installation
when you are working on a tight budget. A "drive compensation" and single bias pot are provided.
The printed circuit board can be split into two or three
pieces to fit into any shape of space.
The mil-spec PS pot is a critical component that makes the overall circuit simple. Additional PS pots must also be of this type. Automated switching selection of these is limited to relays.
The SB-1 can be fitted into any guitar or bass amp with a conventional supply - one where the screen voltage is derived from the plate supply and both voltages are similar. Maximum voltage is limited to 500Vdc.
PCB dimensions: 3.5 x 0.8", 89 x 20mm
splittable into up to three pieces:
two each of 1.1 x 0.8", 28 x 20mm, plus one of 1.3 x 0.8",
33 x 20mm
Kit includes notes with installation tips + layout and schematic diagrams of the kit.
