Bedding in The new preamplifier requires around 200 hours of initial use

(called “bedding in”) before the circuitry becomes stable and

optimum performance is realized.

As the preamplifier “beds in” the sound will become

increasingly smoother, detailed and more open.

Once the amplifier has “bedded in” a warm up time of

approximately 20 to 30 minutes is required each time the

amplifier is switched on before optimum sonic performance is

reached.

Cleaning No special maintenance is required for the preamplifier. Use a

soft, clean lint free cloth to remove any surface marks from the

casework. For finger marks / grease, use a soft, clean lint free

cloth, lightly moistened with a solution of warm water and mild

detergent. Do not use any alcohol or solvent based cleaning

products, as they may damage the finish of the amplifier.

ENSURE THAT THE PREAMPLIFIER IS SWITCHED OFF

AND DISCONNECTED FROM THE MAINS ELECTRICITY

SUPPLY BEFORE UNDERTAKING ANY CLEANING.

Valve Life The valves supplied with your M9 Phono preamplifier should

provide approximately 3 years of operation. They are specially

selected by us, and should only be replaced with valves of the

same type and specification. Please consult your Audio Note

(UK) dealer should your valves need replacing. Alternatively,

feel free to contact us directly.
