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 the meters.
These illuminated meters perform two functions:
•
First, the meters are used to balance the outputs of the third gain stage tubes for the right
and left channels, as explained above in “Initial Set-up”.
Remember, when replacing the
300B tubes be sure to turn the screw for each meter so the needle is on or just below the
left-hand parallel line on the meter’s face. The L-10000 must be powered off to remove
and insert tubes.
•
Second, the meters are indicators of failure or damage to the function of the unit. Any failure
of the tubes or circuits in one or the other of the L-10000 OTL/OCL’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 either meter, it means that
one or both of the third gain stage tubs (300B) for that channel is failing.
• If the needle on either meter moves to the right of the parallel lines, it means that one
or both of the first and second gain stage tubes (6AN8 or 12AU7) 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.
