TRIODE TR1
¥ 280,000 (released in 1998)
Commentary
A pre-main amplifier developed using the vacuum tube technology of triode.
Power MOS-FET 2SK1058/2SJ162 made by Hitachi is used for the amplifier element, and non-feedback circuit is used for the circuit system, making it a class A amplification system.
The power supply is equipped with a toroidal transformer for each channel to reduce interference between the left and right channels.
Equipped with an input / output protect circuit.
6N high-purity wire is used for internal wiring.
The internal layout uses a symmetrical configuration with independent left and right sides.
The front uses two layers of machined aluminum panels, and the handle is designed on the front panel.
High-grade power cable μ -PS15 of Furukawa Electric is used for the power cable.
Legs are equipped with special TAOC insulator.
Wireless remote control is included.
