Krell Industries Power Amplifier KST100 Owner's Reference Manual page 13

Q. After the amplifier is playing for about one hour it
becomes very hot. Is this normal?
A. Yes. Due to the design of the KST-100 it will become
quite warm when driven hard. If the amplifier should
have a severe temperature inbalance between the left and
fight channel, unplug the unit and call your authorized
dealer or Krell.
Q. I tried a ne.w. preamplifier in my audio system and
when | turnecl ttle unit on tlae KST-100 shut off. Is the
amplifier defective?
A. More than likely the amplifier is not defective. When
connecting components you should always keep the
amplifier off. The amplifer sensed a bad input signal and
slaut off, protecting itself and the speakers.
There also could have been a bad cable connection or
excessive DC offset coming from the output of the. pre-
amplifier. Before turning t, he amplifier on, check tlae
input cables. If that doesn t help, bring the preamplifier to
the dealer for testing.
