Chapter Two: Using Your Schmidt
2.1 Mains Connections, Power and Standby
2.1.1 Mains/Connection to Power Outlet
Please make sure that both switches (Power and Standby) are in the off position
before connecting to the mains circuit. Verify line voltage before connecting the
power cord. Never start Schmidt without connecting speakers to the proper
terminals. (See 3.2.5)
2.1.2 Power up, Warm up, Standby off
First, turn the Power switch to on (facing up). The indicator light will turn on. This
starts the tube heating process. After about 40 seconds, the tubes should be
sufficiently heated for normal operation. Your Schmidt is then ready for operation
and the standby switch can be turned to “run” (also facing up). Premature
activation of the standby switch will lead to unnecessary tube stress and
subsequent reduction of the power tube’s life span.
2.1.3 Power Tube Caution
Tubes are electronic components that function only with vacuum intact and under
very high operating temperatures. Each tube has one or more heating filaments,
much like a light bulb. These filaments heat up the anode of the tube. If you switch
the standby switch to the “run” position before these anodes have reached their
operating temperature (when the anode surfaces are not heated evenly), this
causes undue stress to the tubes and their related components inside the amp.
Always give the amp its much needed warm-up time, even if musical inspiration
hits you with a full force.
