6. Operating the Unit

6.1. General Operation

Before turning on each Absolare Push Pull Mono Amplifier, be sure that all tubes are
installed and all cables connected correctly.
If you have changed 845 output 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 each Amplifier on, the power indicator LED on the front face plate will
start to blink. You will not hear any sound until the indicator LED stops blinking to
illuminate continuously which indicates all the capacitors are charged and internal
voltages are stabilized.
Absolare Push-Pull Mono Amplifiers will be ready to operate approx. 40 seconds
after turning on the power and attain full sonic performance in 15 to 30 minutes.
