6. Operating the Unit

Before turning on each Absolare SET 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 the adjustment screws counter-clockwise) before turning-on the amplifiers

and then re-adjust the bias settings. Please refer the bias settings section (6.2).

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 SET Mono Amplifiers will be ready to operate approx. 40 seconds after

turning on the power, but attain full performance in 15 to 30 minutes.

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