Page 3: Introduction
The output transformer is a revolutionary new design by David Manley which is wound on the Manley Labs factory premesis. Its stellar performance will be obvious upon first listening.

Page 4: Mains Connections
MAINS CONNECTIONS 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.

Page 5: Connecting Your Amplifier
CONNECTING YOUR AMPLIFIER Setting up your amplifiers is rather easy. 1. Connect all source components (turntable, CD, Tuner, Tape DAT, etc.) to your preamplifier. 2. Connect the interconnects from the output of the preamplifier or switching center to the RCA input on the top rear of the amplifiers. IF your source has a truly BALANCED output, connect TO the XLR input and select the balanced input. - Page 6 INPUT OUTPUT TUBES:10 x RUSSIAN EL34G The EL34 type we recommend are the Russian up-rated EL34G. This has been proven to be the most rugged and reliable of this type and we strongly emphasize that only the RUSSIAN EL34G's should be used in this amplifier. The MANLEY 250/100 WATT MONOBLOCK has been thoroughly optimised around this tube.
