Bias Adjustment

Your HD100 comes from the factory biased for JJ

justments are not intended to be user-serviceable. Attempting to adjust

the bias yourself will expose you to very dangerous high-voltage elec-

tricity that can kill you. Special test equipment and knowledge of amp

circuits and tubes are required to perform this function. DO NOT AT-

TEMPT TO DO THIS YOURSELF.

Make sure you turn your amp off when you switch tubes and be careful,

the tubes might 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:

1) Do not remove the back panel.

2) Do not attempt to check or replace tubes yourself. Refer to an

authorized service center.

3) Never touch the tubes while the amplifier is turned on or has re-

cently been turned ON. You can severely burn your fingers and

hands.
