CURRENT METERS 

 
As previously noted, there is one current meter for each channel on the front of the L-9000 (See 

Figure 4). These meters indicate the potential for DC from the output of the third gain stage tubes, 

the 6080s. The needles of the meters should be between 10 o’clock and 2 o’clock. However, because 

of the floating power supply circuit, even if a needle falls to the extreme left or right of a meter, 

there is no danger to the connected amplifier or speakers because any possible DC leakage will be 

so small it cannot do damage; in fact, it can hardly even be measured. The variations in readings are 

due to the characteristics of individual tubes; no two tubes are exactly alike in every way. 

 

If a needle falls to the extreme left or right of the meter, try switching the 6080 tube of the channel 

showing the drop for the one in the other channel. If that still does not rectify the situation, one or 

both of the 6080 tubes may need to be replaced. 

 

Within the tube warranty period, if any 6080 tube is outside spec as described above, please contact 

your  Allnic  dealer  or  other  authorized  Allnic  representative  for  assistance.  Outside  the  tube 

warranty period, Allnic Audio and its authorized representatives are still available to consult for 

advice. 

 

 

TUBES 

 

The L-9000 OTL/OCL uses the following tubes (see Figure 5): 

 

 

Two (2) x 6U8A 

 

Two (2) x 12AU7 

 

Two (2) x 6080 

 

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 Audio and 

its authorized representatives are not liable in any way whatsoever for any injury or loss incurred 
by the user or for damage to the L-9000 OTL/OCL, any of its parts, or tubes or replacement tubes 

resulting from the user changing or attempting to change tubes.
