Manley 100/200 WATT MONOBLOCK AMPLIFIER - Manual (Page 8)

OPERATIONAL NOTES
SWITCHING ON
The power switch is located on the lower left hand corner of the front panel. Push the top
of the rocker switch (1) to turn on the amplifier and the bottom of the rocker to turn off the
amplifier. The LED on the right side of the front panel will illuminate indicating that the
amplifier is operating.
RUNNING
It is not recommended that you leave your amplifier permanently switched on. This only
wastes electricity and tube life. Your amplifier has solid state rectification and reaches
peak operating condition in approximately 30 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 amplifier checked
every 3-4 years, depending on usage.
PANEL LAMP
The lamp which illuminates the front panel insert is easily replacable should it ever burn
out. To replace it use only the same type with the same or greater voltage rating. In these
amplifiers, the lamp is a FUSE LAMP STYLE 8V 0.15mA. Dimensions are 1/4" x 1 1/4".
To replace the lamp, turn off and unplug the amplifier. Remove the bottom cover and
locate the lamp holder which sets behind the pront panel insert. Carefully pry out the old
lamp from the clips and firmly replace with the new lamp of the same type and rating.
Replace the bottom cover.
