TUBES

The HPA-5000 XL uses the following tubes (See Figure 3):

• Four (4) x NOS 7233 triode

• Two (2) x NOS E-180CC double triode

• Two (2) x NOS 6AN8 triode-pentode

All consequences of changing or attempting to change tubes are borne by the user unless by express

agreement between the owner and the owner's Allnic dealer. 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 HPA-

5000 XL, any of its parts, or tubes or replacement tubes resulting from the user changing or attempting to

change tubes.

TUBE BIAS

Tube bias is monitored by viewing the meter for each of the right and left channels, located on the top of the

chassis (See Figure 3). Bias is correct if the meter's needle is in the center section of the meter, between the

green and red sections. Tube biasing, if required, is performed by using a small screwdriver to rotate the

yellow bias screw directly above the relevant meter so that the meter needle is in the center section of the

meter, between the green and red sections.
