Build

  • Nice silver mica caps
  • Real SBL-1 mixer
  • Build was tough due to very small pads on the PCB
    • Particularly tough to solder ground pads
    • Pad shapes were not round so less area to set soldering iron
  • Pin 1 orientations on the mixer and oscillator "backwards" from other board legends
  • My kit was missing the center cap of the band filter (150 pF)
