TUBES AND TUBE BIAS

Each A-5000 NEO uses the following tubes:

 Two (2) x 300B

 One (1) x 6GV8

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

necessary to use a matched pair in the A-5000 NEO.

If the current meter, when switched to one or the other of

the unit's 300B's, 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 the 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-5000 NEO 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-5000 NEO, 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 6 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
