Thank you for purchasing the TUBE53.

Please refer to this Owner's Manual to use your TUBE53 safely, and in the best pos-

sible way. It is recommended that you keep the carton box and the packing material

available for future transportation needs.

• Though it is a vacuum tube ampliﬁer, the TUBE53 achieves a 20W + 20W (8Ω)

output and high response, that can drive the analog signal with ease from even

digital media players.

• The TUBE53 uses two 6L6GC tubes per channel in a push-pull conﬁguration, and

low-distortion Mullard type phase inverting circuitry design.

• The TUBE53 achieves hi-ﬁdelity music reproduction with minimum reliance on

negative feedback circuitry.

• The output transformer, which uses orient core materials, achieves a straight

sound quality with minimum phase misalignment. The TUBE53 uses a troidal

transformer, featuring superior rise characteristics, for its power supply. Noise is

thoroughly eliminated by solidifying the transformer with resin and covering it

with a steel casing.

• The TUBE53 uses selected high quality components to draw out the circuitry's

full potential, such as low-distortion volume control, electrolytic capacitors and

resistors with high information processing ability and low noise.
