accomplished.
8. Balance the cathode point of the R-channel monoblock with respect to the
filament of the installed 845 tube in a similar manner. Power off the R-amplifier
after the balancing procedure has been completed.
Check the amplifiers for correct cathode point balance from time to time and finely tune
the balance if necessary!
Always re-balance the L R amplifier after changing the 845 power tube!
9. Connect the L+R amplifier to the preamplifier.
10. Make sure that the volume control kno rests in zero position.
11. Power on the preamplifier and the program source(s) while the R+L power
amplifier is powered off. Wait until the warm-up process on these components has
come to an end.
12. Complete the setup y powering on the L+R power amplifier.
Always power on the program sources and the preamplifier first and then switch on the
SE845 power amplifiers, observing a delay of at least 30 seconds!
When powering off the system, always switch off the power amplifiers first, then switch
off the other components of the system, observing a delay of at least 30 seconds!
Keep the original crates and tube protection cases for later use. They have been
specifically designed for safe transport under rough conditions!
