Bias Adjustment
Your Dream Amp comes from the factory biased for EL34 or 6L6GC tubes. Bias adjustments are not
intended to be user-serviceable. Attempting to adjust the bias yourself will expose you to very dan-
gerous high-voltage electricity that can kill you. Special test equipment and knowledge of amp cir-
cuits and tubes are required to perform this function. DO NOT ATTEMPT TO DO THIS YOURSELF.
Tube Replacement
WE RECOMMEND TAKING YOUR AMPLIFIER TO A QUALIFIED TECHNICIAN FOR SERVICING YOUR
TUBES. Make certain the amplifier is turned off and has been allowed ample time to cool down. Be
very careful when you remove the tubes as they might still be very hot! Do not touch tube sockets
with fingers! 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.
WARNING:
• Do not remove the back panel.
• Do not attempt to check or replace tubes yourself. Refer to an authorized service center.
• Never touch the tubes while the amplifier is turned on or has recently been turned ON. You can
severely burn your fingers and hands.
