Swapping Tubes and Bias Adjustment
Your KITCHEN SINK 6VEL comes from the factory biased for safe operation of the factory provided
tubes. Limited bias adjustments are available to the user via the back panel bias terminals. Follow
the recommended procedures and bias settings at all times and note the highlighted warning and
caution alerts as your safety as well as the safe operation of your amplifier depend on it.
The operating range of the user bias circuit has been limited as a precaution while retaining enough
adjustment potential in order to provide the necessary flexibility to operate a wide range of
compatible tubes available on the market.
Under no circumstances should you open your amplifier and attempt to modify the circuitry in order
to increase operating range. Attempting to do so will potentially expose you to very dangerous
high-voltage electricity that can kill you. DO NOT ATTEMPT TO DO THIS YOURSELF.
Tube Replacement
THE SAFEST WAY TO CHANGE YOUR TUBES WOULD BE TO TAKE YOUR AMPLIFIER TO A QUALIFIED
TECHNICIAN FOR SERVICING. To safely change your own tubes at home: Make certain the amplifier
is turned off and has been allowed ample time to cool down.
WARNING:
Never touch the tubes while the amplifier is turned on or has recently been turned ON. You can
severely burn your fingers and hands. Tubes are made of glass and can break if mishandled.
WARNING:
Do not touch the tube pins as you remove the tube. Even after turning your amp off and unplugging
it from the power outlet there could be enough voltage stored in the capacitors to give you a lethal
electrical shock.
