LUXMAN SQ-38Signature Tube Integrated Amplifier used 1995 JAPAN

  
LUXMAN SQ-38Signature Tube Integrated Amplifier. The company's 70th anniversary model. Output tube EL34 (6CA7) is operated by push-pull. De The Williamson circuit is adopted as a power amplifier part. An inverted signal is formed by PK division with little sound quality degradation, and the output tube EL34 (6CA7) is operated by push-pull, and the total NFB is kept to a little. The output tube EL34 has been carefully selected and adopted from the Golden Dragon company special line, and has an orthodox element and circuit configuration such as using 12AU7 for the first stage and 12BH7 for the driver stage. The traditional OY type which decided the evaluation of the Lux as a transformer maker is adopted as the output transformer which has a great influence on sound quality. Orient core material is used, and new design is performed according to the specification based on OY's original split winding. Thereby, in addition to the outstanding sound quality with few phase rotations, the obedient response which extended to the low-pass and the audible band was acquired. In addition, the transformer body is tightly shielded, filled with a fixing material, and then stored in an iron case to completely eliminate leakage flux. The pre-volume is equipped with a custom volume control that improves distortion and improves sound quality. The tone control circuit consists of a vacuum tube 12AU7. In this circuit, a more natural correction is possible by making the high range and the low range independent. Thorough attention is also paid to basic parts, and consideration is given to sound quality, such as using a newly improved composite electrolytic capacitor, high-precision mold resistance, and double-sided glass epoxy type circuit boards. Source select can switch line input and tape input / output independently.

In addition, if you use a 3 head deck, you can monitor simultaneously when recording with the monitor switch. In addition, the line straight switch allows you to jump over the monitor switch and balance volume and send the source signal in a more pure state.

In order to correspond also to CD, DAT, etc. Four line inputs are carried. A high-accuracy phono equalizer is also built-in. In order to fix the vacuum tube securely and eliminate the influence of external vibration, the chassis is given a moderate weight to create a highly rigid structure.

In addition, consideration is given to vibration suppression measures such as using high-density materials for the side panels and using materials with different vibration modes. The knobs for volume control and selector switch are a combination of blasting and hairline processing. The AC inlet is adopted as a power cable. In addition, the line phase sensor can be used to manage the polarity.
