OPERATION
From this point on, operation is straight-forward. All functions are controlled from the front
panel or the remote control. Of course, BE CAREFUL about differences in gain between your
sources. Generally, disc players and tuners will have greater gain than phono stages. That means
the volume setting for listening to your turntable might be too high for listening to CDs or
streaming devices.
To avoid surges to the speakers, it is best to change from input to input only with the "operate"
button set to mute (the light above the button will not be illuminated when the button is in the
"mute" position).
When you are finished listening, turn off your stereo power amplifier or mono-block amplifiers.
Then turn off the L-8000 DHT by depressing the power button on the front panel. The power
switch on the left side panel should stay in the "on" position – this will keep key circuitry warm,
and your L-8000 DHT will be ready to play when the soft-start turns on the L-8000 DHT next time
you want to listen. Turn off your sources last.
THE CURRENT METERS
These illuminated meters indicate the current supply to the gain tubes in the L-8000 DHT. They
are indicators of failure or damage to the function of the unit. There is one meter for each
channel. The needle should be between the two parallel lines just left of centre on the meter
face. Any failure of the tubes or circuits in one or the other of the L-8000 DHT's channels is
indicated by the needle on the meter for the respective channel moving out from between
those two parallel lines.
If the needle has moved to the left of the parallel lines on a meter, it means that one or
•
both of the gain tubes (3A/110A or 3A/109B) for that channel is failing.
•
If the needle on either meter moves to the right of the parallel lines, it means that one or
the other of the rectifier or voltage regulator tubes (7233 or 5654) for that channel is
failing.
In the case of any failure indicated by the meter, please contact Allnic Audio or its authorized
representative for assistance.
TUBES
The L-8000 DHT uses the following tubes (see Figure 5):
Two (2) x 5654
•
Two (2) x 7233
•
Two (2) x 3A/110A (or MR0 PT8, if requested for lower gain)
•
•
Two (2) x 3A/109B
All consequences of changing or attempting to change tubes are borne by the user unless by
express agreement between the owner and Allnic Audio or its authorized representative. Allnic
