Manley The WAVE DAC/Preamp 20 Bit Version Serial Code WAVE000-015 1999 - 2002 - Manual (Page 4)

OPERATIONAL NOTES
SWITCHING ON
All cables should be pre- connected to the WAVE especially the EXTERNAL POWER
SUPPLY cable and interconnects to the power amps and the AC mains.
The power switch is located on the back panel of the EXTERNAL POWER SUPPLY. You
shouldn't need to turn the supply around or get yourself behind it. You should be able to "feel"
the rocker switch located next to the AC power cord. Flip the switch away from the power cord
to turn on the Wave or towards the power cord to turn off the unit.
RUNNING
It is not recommended that you leave your Wave stay permanently switched on. This only
wastes electricity and tube life. We provide a STANDBY switch which effectively turns the
Wave off. The Wave reaches peak operating condition in approximately 15 minutes.
TUBE LIFE
As with all tubes, their quality degrades with age. This is due to cathode emission, a natural
process found in all tubes. We recommend that you have your preamplifier checked every 4-5
years, depending on usage. An excessive increase in noise level can indicate the need to replace
a tube.
REPLACING A TUBE, INDICATOR LAMP or FUSE. You should read page 10 for more
details if you need more specific info. You may need a small Phillips screwdriver and the
correct replacement fuse, tube or lamp. First be sure the unit is off and remove the IEC mains
cable. Let it sit for 15 minutes to be sure all power supply capacitors are discharged otherwise
one could still get a shock even though the unit is unplugged. If you are changing a tube or
lamp, be sure that it the same number or is on the list of possible substutions. Gently wiggle the
tube around while pulling it out of the socket. Avoid bending the printed circuit board. Before
putting a new tube in, look at it. Check to see that the pins are straight and that they line up to
the socket. You should be able to gently push the tube into the socket without excessive force.
Changing these tubes should be a rare event and should be accompanied by a re-calibration.
