INSTRUCTIONS FOR OPERATION
PLEASE READ BEFORE PLUGGING IN THE UNIT
Welcome!
The Wright Audio Integrated Amplifiers incorporate advanced circuit characteristics and parts, which have been chosen
based on sonic quality and reliability.
Please take a few moments to read this manual. Doing so will enable you to thoroughly enjoy your new amplifier's sonic
quality and fully utilize its versatility. First, a few cautions. Most are common sense, but are here as reminders. These
apply to all tube and most solid-state amplifiers and are not specific only to your Wright Audio Amplifier.
1. Never operate the amplifier unless speakers are attached to its outputs.
2. Do not attempt to connect a subwoofer crossover / amplifier / speaker to the speaker terminals.
3. Never switch or disconnect input cables while the amplifier is on AND the volume turned up. Doing so
may damage your speakers.
4. Any modifications to the amplifier's circuitry voids the warranty. Tampering with the warranty seals voids the
warranty.
5. Tubes must be replaced at the end of their useful listening life, which is about 2000 hours, or approximately
every 2 to 3 years of 'average' use. Operation past this point increases the risk of complete tube failure
which may require amplifier repair.
6. The tubes get hot in normal operation. Touching one can result in a minor burn.
7. Do not attempt to change or remove a tube while the amplifier is on.
8. This amplifier utilizes a vacuum tube rectifier, the GZ34 / 5AR4. Whenever the amplifier has been turned off,
wait at least 5 minutes before turning the amplifier on again to allow it to cool. Not doing so stresses the tube.
9. Always install tubes of the identical numbers as shown on the sticker on the amplifier's bottom plate.
Inserting ANY other tube number will cause unsatisfactory operation and will probably damage the amplifier.
Tube numbers are always shown on the tube and tube box.
10. Do not open the bottom cover of the amplifier. Lethal voltages exist within, even when the power cord is
disconnected from the socket. Only a qualified service technician familiar with vacuum tube technology
must service your amplifier. Preferably, it should be returned to Wright Audio if there is a malfunction.
11. Connect the unit to an electrical outlet providing 50 to 60 cycles AC and the voltage marked on the amplifier.
12. This unit has been provided with a 3-prong grounding plug. This arrangement is utilized as an added
measure of safety.
