Front Panel Controls
The front panel controls are (left to right) the 3-position Source selector switch (Line1-
Line2-Line3), Mode switch (Stereo or HT), Volume control, and Balance control. In HT
mode, the selected input source is connected to the output jacks and the active preamp
output is disabled; the power may be turned off.
Remote Volume Control
The volume control IR sensor is located between the volume and
balance control as shown above. The remote handset has buttons for
volume up and down. The power button is disabled. When first
turning on the power supply, the volume control will reset to zero and
then advance to the 9 o’clock position. It is designed to avoid
unexpected high volume levels when powering up.
Tubes_____
The tubes supplied are new-old stock (NOS) and have been pre-tested. A burn-in period
of several hours may be needed to achieve the best sonic performance. Tube life should
be thousands of hours. Aging tubes may result in a reduced gain in one or both channels
or an increase in noise levels. Infrequently, a heater may burn out which is indicated by
total loss of sound. Replacement tubes can be obtained from several suppliers in the U.S.
and Canada. Some listeners enjoy trying different brands and variants of tubes. The
heater voltage selector switch permits the use of 6SN7GTB (or the 5692 special red
version) tubes of NOS or current manufacture. The highly regarded 12SX7GT is
equivalent to the 12SN7GT.
