INTRODUCTION
THANK YOU!...
for choosing the Manley DIRECT INPUT 50/50 Amplifier. Designed by David Manley, the Manley DIRECT INPUT 50/50 Amplifier uses only the best available components, with the shortest and cleanest signal path possible, and with the use of our own
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 for the more powerful tetrode operation mode with a separate regulated screen supply which allows a wider range of EL34s to be used as the screens are run at safer lower and constant voltages . 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
Thank you again, and please enjoy!
GENERAL NOTES
LOCATION & VENTILATION
The Manley DIRECT INPUT 50/50 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. 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.
WARNING! !
TO PREVENT THE RISK OF ELECTRIC SHOCK
DO NOT OPEN THE CABINET
