When you are finished listening, turn off your power amplifier(s); then turn off your
preamplifier and then turn off the H-6500 last by pressing the on-off switch on the front
panel of the power supply so it returns to the out position.
In the case of any failure, please contact your Allnic Audio dealer for assistance.
CURRENT METERS
These illuminated meters indicate the current supply to the gain tubes in the H-6500.
They are indicators of failure or damage to the function of the unit. There is one meter
for each channel. The needle should be between the two parallel lines just left of centre
on the meter face. Any failure of the tubes or circuits in one or the other of the H-6500'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 a meter, it means that a
gain tube (5842) 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 voltage regulator/error detector tubes (7233 and 5654) for
that channel is failing.
In the case of any failure indicated by the meter, please contact your Allnic Audio dealer
for assistance.
The H-6500 has been designed so that if a tube (or tubes) fails it is not necessary to
replace all the tubes of that type with a matched set of the same type. It is necessary to
replace only each failed tube with a good tube of the same type.
TUBES
The H-6500 uses the following tubes:
Eight (8) x 5842 (4 per channel)
•
Two (2) x 7233
•
Two (2) x 5654
•
One (1) x 5AR4 (in, and the only tube in, the power supply)
•
All consequences of changing or attempting to change tubes are borne by the user
unless by express agreement between the owner and Allnic Audio. Allnic Audio,
Audiomentors and Allnic's dealers will not accept any liability whatsoever for any
injury to the user or damage to the H-6500, any of its parts, or tubes or replacement
tubes resulting from the user changing or attempting to change tubes.
