Kondo Audio Note Japan has introduced the new GE-7i vacuum tube phono preamplifier. The manufacturer emphasizes that the new product is neither a simplified version of the GE-10 model, nor an improved version of the GE-1 phono preamplifier, but offers its own new solution in the field of ultimate correction of the signal from a vinyl record. In the NF type equalization circuit, the SRPP input stage is implemented on the ECC803S tube.
Due to the use of a parallel cathode follower on the 6072 tube at the output, the output impedance is reduced, which ensures accurate sound reproduction. Like the flagship GE-10, this model uses a shunt-type filament power supply circuit and a smaller power supply housing so that together with the phono preamplifier the width does not exceed the standard size of Hi-Fi components of 480 mm. The shunt-type filament power supply has been redesigned to meet new needs. The shunt type regulator circuit ensures that the filament voltage will not change within 5% of the power supply voltage fluctuation, making it an extremely stable power supply circuit.
Features of the Kondo Audio Note Japan GE-7i Phono Preamplifier:
The Kondo Audio Note Japan GE-7i vacuum tube phono preamplifier incorporates high-quality original components such as a copper main chassis, pure silver foil capacitors, pure silver resistors, SSW wiring, silver shielded cables, silver-palladium plated RCA jacks, and zirconium tube pads. In addition, the circuit uses custom-made electrolytic capacitors, power transformers, and chokes.
