GALA
GALA is a power tube amplifier no compromise, which is made in two units, one power supply and one power amplifier.

GALA is a power tube amplifier no compromise, which is made in two units, one power supply and one power amplifier.
Both of them are entirely with tubes. The power supply includes:

  • One stabilized circuit high voltage 360V 300mA
  • Four stabilized circuits low voltage: two 5V 2A, one 12V 1A, one 80V 50mA.

The power amplifier includes both channels, left and right.
Each of them is a push-pull of triodes 300B working in class A over the whole power and frequency range. The separation in two units allows:

  • To reduce the electric noise
  • To mantain quite low operation temperature of the audio stages
  • To eliminate the coupling of the transformers fluxes

GALA has the following additional characteristics:

  • No negative feedback
  • Stand by function
  • Automatic adjustment of BIAS: an electronic device mantain the BIAS within ±1% of the nominal value
