6. Operating the Unit

6.1. General Operation

Before turning on the unit be sure that all tubes are installed and all cables

connected correctly.

If you have changed 845 tubes you should first minimize the bias settings (by

rotating to counter-clockwise) before turning-on the amplifiers and re-adjust the bias

settings. Please refer the bias settings section (6.2.1).

After turning on, the power indicator LED on the front plate will start to blink. Sound

will only be audible after all capacitors inside are charged and internal voltages are

stabilized (after that the indicator LED starts to illuminate continuously).

Absolare Push-Pull Amplifier will be ready to operate approx. 40 seconds after

turning on the power, but attaining full performance may take 15 to 30 minutes.

6.2. Setting the Bias Levels

Measurement points for the bias levels are at the back cover:
