INTRODUCTION

THANK YOU!...

for choosing the Manley LAB SERIES STEREO 75 + 75 watt Amplifier. Designed by David Manley, the Manley LAB SERIES STEREO 75 + 75 watt Amplifier uses 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. 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 solid-state 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 LAB SERIES STEREO 75 + 75 watt Amplifier 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.

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!
