INTRODUCTION!THANK YOU!...
for choosing the Manley Euro 100 Stereo Amplifier. Designed by David Manley, the Manley Euro 100 Stereo
Amplifier uses 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 a amplifier that looks as good as it sounds. For this
amplifier design, we have chosen an interesting Russian military tube, the GammaY50. 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 ULTRALINEAR or "partial-triode"
operation which achieves the seductive quality of triode operation without the inefficiency and sacrifice in power
of triode operation. 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. The output transformer has been
factory set in series-parallel for an optimum 5 ohm load which will drive most speakers. Other output impedances
can be achieved by changing the configuration of the transformer secondary. Please contact us at the factory should
you need to do this.
Thank you again, and please enjoy!
GENERAL NOTES
LOCATION & VENTILATION
The Manley Stereo 100 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 constant movement of air can flow. Do
not place amplifiers directly on high pile carpet or any other surface that will block the ventilation holes
underneath the amplifiers. If you have small children or pets, you should consider placing the amplifiers out of
reach or using the optional cages (covers) available as an option 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, this amplifier should not be used near water or moisture. If liquid enters the
amplifier, it must be immediately returned to your deal 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, 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.
WARNING!
TO PREVENT THE RISK OF ELECTRIC SHOCK
