Flatstone Amplifiers were designed with the working musician in mind. All amps are designed for industrial grade reliability with American made audiophile grade components.

  • Finger jointed select grade white pine boards selected directly from Northern Wisconsin sawmills for warm, woody vintage tone.
  • 18 ga. yellow zinc plated steel chasis, wirefeed welded.
  • Point to point handwiring on 1/8" thick epoxy glass solder eyelet circuit boards.
  • All circuit board components are designed with immediate, unobstructed access in mind.
  • No plug in connectors or ribbon cables in amplifier to come loose or corrode.
  • American made Sprague and Mallory filter and signal capaciters and 1 watt resistors on pre-amp tube plates.
  • Vacuum tube rectifiers in all Flat Stone Amps power supplies for the warmest tone and natural sustain you can get from a tube amp.
  • All electronic components are on a single circuit board and in a logical order for shortest wiring leads resulting in noiseless and stable operation.
  • Jensen re-issue C12N speakers. They speak for themselves.
  • Full size chasis mounted potentiometers with 1/4" metal shafts and 3/8" mounting bushings.
  • Black enameled brass, engraved faceplate with cream pointer set screw style knobs.
  • Large selection of tolex and grill cloths.
  • American made Switchcraft metal jacks and plugs.
