Wright Audio LT - 6P Instructions

Please take a few moments to read this manual. Doing so will enable you to thoroughly enjoy your
new preamplifier's quality and fully utilize its versatility. But first some cautions. Most are common
sense, but are here as reminders. These cautions apply to most tube and solid-state amplifiers, and
are not specific only to this product.
PLEASE NOTE: This preamplifier has been designed NOT to produce signal transients
during start-up or shut down. However, a faulty part or other conditions may cause a
transient to be passed to a solid-state power amplifier. To avoid costly damage, get in
the habit of turning the preamplifier on first and letting it warm up for a minute before
you turn on your solid-state power amplifier.
When shutting down, it is best to turn off the power amplifier before the preamplifier.
1. Connect the unit to an electrical outlet providing 50 to 60 cycles AC and the voltage
marked on the back panel. The unit will operate satisfactorily when operated within
5% of that shown on the unit. Any other voltage will void the warranty.
2. These units have been supplied with a 3-prong grounding plug. This arrangement
is utilized as an added measure of safety. Do not defeat its purpose in any way.
3. The power cord should be unplugged from the AC outlet when the unit will not be
used for an extended period of time.
4. The unit must not be exposed to excessive moisture.
5. The tubes, particularly the 5AR4, become warm to hot in normal operation.
6. Never switch or disconnect input or output cables while the system is turned on.
Doing so may damage your speakers.
7. Opening the unit voids the warranty.
8. Tubes must be replaced at the end of their useful listening life, which is about
4000 hours, or approximately 5 years of 'average' use. Operation past this point
will likely not provide quality sound. Wright Audio always supplies the proper
replacement tube types at reasonable prices.
9. Do not open the cover. Lethal voltages exist within, even when the power cord is
disconnected from the outlet. Preferably, it should be returned to Wright Audio if
there is a malfunction.
10. Always install tubes of the identical numbers as shown on the unit's bottom plate.
Inserting any other tube number may likely damage the tube and possibly the
preamplifier. Tube numbers are always marked on the tube. If in doubt of a
suitable tube type to use, please contact us.
