GAIN STAGE BALANCING USING THE CURRENT METERS - IMPORTANT!
There is one current meter for each channel on the front of the L-10000 (See Figure 4). These
meters indicate the status of the current supply to the gain tubes in the L-10000 OTL/OCL. If the
gain stages are set up and functioning properly, the needles of the meters should be in the centre
between the two parallel lines in the middle of each meter.
The meters have two functions, but initially, and from time to time as may be necessary (this
should be very infrequently, if ever, for example, when replacing the 300B tubes), they are used
to balance the outputs of the third gain stage tubes for the right and left channels.
Using a small, flat blade screwdriver, turn the screw head located immediately above each of the
meters on the L-10000's face (see Figure 4) clockwise and counter-clockwise until the meter's
needle is centred between the parallel lines in the middle of the meter. The goal is to have the
needles of both meters in the centre position between the two parallel lines. Please be patient;
it could take some time to get the balance, but once set, it should rarely, if ever, move.
The Allnic Audio L-10000 OTL/OCL is now ready for operation. At this point, you can power on
your sources and, finally, your stereo power amplifier or mono-blocks.
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 digital disks 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-10000 OTL/OCL 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-10000 OTL/OCL will be ready to play when the soft-start turns on the L-10000
OTL/OCL next time you want to listen. Turn off your sources last.
