OPERATING PRECAUTIONS
To ensure safe and reliable operation please regard the following precautions:-
HIGH VOLTAGES CAN BE LETHAL. Never try to operate your amplifier with the
covers removed. If it is necessary to work inside the cabinet, always disconnect the
Mains supply and allow the capacitors to discharge fully.
Never operate the amplifier into a load or antenna with an SWR greater than 2 : 1.
Always tune the amplifier for resonance using low drive at the operating frequency.
The components in the amplifier are designed to be used within the parameters of the
specifications on page 2. Excessive drive giving output in excess of these specifica-
tions will shorten valve life and could affect the reliability of other components.
