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.
