INTRODUCTION

THANK YOU!...

for choosing the Manley 50 Watt Monoblock Amplifiers. Designed around the concept that less is
more, the Manley 50 Watt Monoblock Amplifiers use only the best available components, with the
shortest and cleanest signal path possible, and with the use of our own milling equipment we can
provide you with an amplifier that looks as good as it sounds. We have developed a magnetics
winding department right here at Manley Labs where we design and wind the audio transformers.
David Manley has invented a brand new winding technique for the output transformer which exactly
preserves equality in the push-pull halves of the output stage. This breakthrough has once again put
Manley Labs on the leading edge.

Thank you again, and please enjoy!

GENERAL NOTES

LOCATION & VENTILATION

The Manley 50 Watt Monoblock 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 amplifier, such
that a constant flow of air can flow throughout the ventilation openings. We also recommend that
the amplifier and preamplifier be placed at least 10 inches apart. Do not place amplifiers directly on
high pile carpet or any other surface that will block the ventilation vents.

WATER & 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, NEVER touch the tubes after the amplifier has been
switched on, the tubes become very hot during operation and should only be handled after the power
has been turned off and the tubes have cooled.
