Maintenance
GTQ amplifiers do not require any
regular maintenance. Periodically
checking the main power supply and
grounding points and terminal
connections is advisable. Be sure the
connections are solid and corrosion-free.
Loose or corroded connections can cause
annoying intermittent noise or unusual
operational problems. Do not allow dust
to accumulate on the amplifier heat
sinks. It will reduce the amplifier’s ability
to dissipate heat. Occasional vacuum-
cleaning will prevent dust accumulation.
