Congratulations on your purchase of the Audio Note Meishu Line Integrated Amplifier.
The Meishu is a Pure Class A Singled Ended valve amplifier that uses the highly
regarded 300B direct heated triode valve. The Meishu produces a level of performance
that is radically superior to current designs and was specifically designed for sonic
performance rather than technical specifications. It also fulfills all Level 3 criteria.
-Pure Class A operation.
-Zero Negative Feedback.
-Single Ended Output Stage.
-Valve Rectification.
-Directly Heated Triode.
-Materials and component quality.
The Silver version features Audio Note Silver wiring, Audio Note Copper Foil signal
capacitors, Black Gate electrolytics, Tantalum film resistors and High B C-core output
transformers.
UNPACKING AND INSTALLATION
The amplifier is shipped without the 3 large valves installed. It is necessary to install
the valves first. It is essential that the valves are installed correctly or serious
damage that is not covered by the warranty will result. We recommend that your
dealer does this for you if you are unsure.
Please take the time now to fill out and send in your warranty card. This will serve as
proof of purchase and ensure that all warranty work if ever needed is completed in a
timely fashion.
Installing the valves
Please take care when unpacking the amplifier as it is very heavy and place on a suitable
clean space (table or floor). We recommend that you store the packaging materials in
case the unit requires shipping at a later date.
Use a No.2 pozidrive® screwdriver to remove the top cover of the amplifier, 6 x screws
for the top and 7 x screws for each side. Now remove the 3 valves that are packed inside
the amplifier. Also inspect the inside of the amplifier to check that nothing has become
damaged during transit including the remaining 9 smaller valves.
Carefully unwrap the 3 valves. You will find 2 x 300B and 1 x 5U4G valve.
It is absolutely vital that these valves are fitted correctly.

  • Page 2 Looking from the front of the amplifier install the 300B valves first. Inspect a 300B valve base and you will notice that two of the pins are larger than the other two. This is to help ensure that the valve can only be inserted one way. (1) The larger pins must face each other when fitted to their valve bases on the central board.

These valves are specially selected and carefully matched by Audio Note for use with the Meishu and should only be replaced with matched pairs. Please consult your Audio Note dealer should the performance of the amplifiers deteriorate so that arrangements for valve replacements can be made.
