TUBES AND TUBE BIAS

Each A-6000 uses the following tubes:

 Four (4) x 300B

 One (1) x 6GV8

Because of the individual bias for each 300B, it is not

necessary to use a matched quad in the A-6000.

If the needle of a current meter for a 300B has moved to the

left of the parallel lines on the meter face, using an

appropriately bladed screwdriver, adjust the potentiometer

directly in front of that tube's location by turning it clockwise

until the needle has returned to between the meter's parallel

lines. If the meter needle has moved to the right of the

parallel lines on the meter face, turn the potentiometer

control counter-clockwise to correct.

If a meter's needle drops to the left limit of the meter's face

during operation, this indicates a failure of the related 300B

tube. You must turn off the A-6000 and replace both the fuse

(0.5A, 250V, 20mm glass type) for that tube and the 300B. To

replace a fuse, using a screwdriver, simply turn the top of the

fuse cap counter clockwise. It will spring out holding the fuse.

Replace the fuse, push the fuse cap down and turn it

clockwise; it will lock itself. If you have any questions about

doing this, please contact Hammertone Audio for assistance.

You may use any 300B type tube in the A-6000, including the

newer higher voltage varieties. Of course, you will have to

adjust the bias back into the area between the two parallel

lines of the meter for a tube when it is replaced. Please refer

to Figure 5 for tube locations.

All consequences of changing or attempting to change tubes

are borne by the user unless by express agreement between

the owner and Hammertone Audio. Allnic Audio and
