INTRODUCTION

THANK YOU!...

for choosing the Manley LAB SERIES Monoblock 100 watt Amplifiers. Designed by David Manley,
the Manley Monoblock 100 watt Amplifiers use only the best available components, with the shortest
and cleanest signal path possible.
The circuit and the components used have been chosen carefully after years of development and
refinement for reliability, constancy and most importanly, musical, accurate, and emotional delivery of
the sound. The circuit topology is similar to other designs in the MANLEY range. This amplifier is
configured to switch between triode or tetrode operation which allows the user to choose between the
sonic benefits and seductive qualities of triode and the more powerful tetrode operation mode. We
emphasize big beefy resevoir capacitors in the high voltage supplies giving plenty of instant energy for
dynamic performance of transient peaks and bass performance which often exceeds that of rival solid­state amplifiers. We run high voltages on the plates of the output tubes and are thus able to run them at
lower current which will result in longer life for the output tubes. Each output tube has its own bias
adjust, and the procedure for adjusting each tube's current draw is described in this manual.

GENERAL NOTES

LOCATION & VENTILATION

The Manley Monoblock 100 watt Amplifiers must be installed in a stable location with ample
ventilation. Allow a minimum of 2 inches of clearance on the top and sides of the amplifiers, such that
a constant flow of air can flow. Do not place amplifiers directly on high pile carpet or any other
surface that will block the ventilation vents underneath the amplifiers. If you have small children or
pets, you should consider placing the amplifiers out of reach to prevent damage to the amplifier or
damage to your small children or pets by the amplifier as the tubes do get hot during operation.

WATER & MOISTURE

As with any electrical equipment, these amplifiers should not be used near water or moisture. If liquid
enters the amplifier, it must be immediately returned to your dealer for servicing.

SERVICING

The user should not attempt to service the amplifier beyond that described in the owner's manual.
Refer all servicing other than biasing and tube replacement to Manley Laboratories

SPECIAL NOTES

Tubes may become loose during transit. Straighten and press down each tube before plugging the
amplifier into the mains socket. Furthermore, do not touch the tubes after the amplifier has been
switched on, as the tubes become very hot during operation and should only be handled after the power
has been turned off and the tubes have cooled.
Your amplifier has been factory set to the correct mains voltage for your country. The voltage setting is
marked on the serial badge, located on the rear panel. Check that this complies with your local supply.

Thank you again, and please enjoy!

MAINS CONNECTIONS

Export units for certain markets have a moulded mains plug fitted to comply with local
requirements. If your unit does not have a plug fitted the coloured wires should be connected
to the appropriate plug terminals in accordance with the following code.

GREEN/YELLOW EARTH terminal
BLUE NEUTRAL terminal
BROWN LIVE terminal

As the colours of the wires in the mains lead may not correspond with the coloured marking
identifying the terminals in your plug proceed as follows;

The wire which is coloured GREEN/YELLOW must be connected to the terminal in the plug
which is marked by the letter E or by the safety earth symbol or coloured GREEN or GREEN
and YELLOW.

The wire which is coloured BLUE must be connected to the terminal in the plug which is
marked by the letter N or coloured BLACK.

The wire which is coloured BROWN must be connected to the terminal in the plug which is
marked by the letter L or coloured RED.

DO NOT CONNECT/SWITCH ON THE MAINS SUPPLY UNTIL ALL OTHER
CONNECTIONS HAVE BEEN MADE.
