Description
Product descriptionA complete stereo power amplifier kit that uses the same high-output triode output tube 8045G as the A3000.All stages of the amplifier are designed with emphasis on bare characteristics, and excellent distortion characteristics are achieved by applying 16dB of major NF.8045G is a new joint development between Lux and Nippon Electric in preparation for the high-power era, and uses a 5-layer bonded metal plate with high heat dissipation effect for the plate electrode, and an electrode structure with heat dissipation fins. This results in a plate loss of 45W.In addition, the output transformer uses OY15-3.6K-HP, which was newly developed for A3600. Although this transformer has the same appearance as the conventional OY15 type, the handling capacity has been increased to 50W, making it a high-power specification. Furthermore, insertion loss is reduced and high frequency characteristics are also improved.The driver circuit employs a cathode-coupled phase inversion circuit called the orthodox Mullard type. This method has high stability because the output voltage and gain can be large.In addition, this circuit uses 6240G, which was developed for high voltage drives. This bulb is a dual triode tube with a medium amplification factor and low internal resistance, and has large plate loss, making it ideal for use as a driver tube for high-output power amplifiers. The A3600 has an appropriate difference in plate resistance in order to balance the gain of the upper and lower driver tubes.The first stage uses 6AQ8, which has low internal resistance and a high amplification factor, and prevents deterioration of high-frequency characteristics by keeping the impedance of the plate circuit sufficiently low, and a phase correction circuit that worsens distortion in high frequencies. is eliminated, and excellent high-frequency distortion characteristics are obtained.?Main specificationsModel Tube type stereo power amplifier kitContinuous effective output 50W+50W (4?, 8?, 16?)Total harmonic distortion rate 0.5% or less (50W, 1kHz)1% or less (50W, 55Hz to 10kHz)Frequency characteristics 10Hz to 40kHz within -1dBInput sensitivity approximately 850mVInput impedance 80k?Damping factor 14 (8?, 1kHz)Residual noise 0.5mV or lessVacuum tubes used: 8045G: 4 pieces6240G: 2 pieces6AQ8:1 piecePower consumption 300W400W (at rated output)External dimensions Width 465x Height 168x Depth 206mmWeight 17.0kg?The condition of the product is that it is used and has some scratches and dirt due to daily use.2024.10 Completed maintenance by designated contractor, changed to LED light bulbFor remote delivery areas, additional fees will be charged.
