The Fascinating KT170

Tung-Sol KT170 is an octal-based beam tetrode vacuum tube. It is the 2021 newly released flagship of the KT (kinkless tetrode) tube family.

Audiophiles love the KT family, and the KT88 has maintained a center role since 1956. There were multiple attempts to develop a new vacuum tube for high-end audio, that rivaled the sonic performance of KT88 with higher power.

The KT170 is the latest attempt from Tung-Sol and by far the best attempt based on Cayin's experience with all the KT vacuum tubes currently available.

It features a high-efficiency outboard power supply circuit with substantial power reserves, delivering an authoritative headphone output of up to 18WPC, ushering headphones into a new realm of personal listening experience.

Single-ended Voltage Amplification

After carefully evaluating different alternatives, Cayin decided to use two indirectly heated dual triode 6SN7 to take care of the voltage amplification given its medium (amplification factor) and low internal resistance.

The JJ 6SN7 is impressive for its low noise and balanced tonal balance across the audible frequency ranges. The sound performance is dynamic, with rich details, and offers excellent musical expressiveness.

Outboard Power Supply Design Empowering with Ample Energy

Physically separated 2 box design, the outboard power supply delivers clean, low-noise electrical power to the amplification circuit in a separated chassis independently. It also provides better heat dissipation even when stacked up, allowing the users to place the amplifiers with flexibility.

Dual power supply transformers deliver high and low voltage separately, minimize electrical interference, and safeguard clean power to the amplifier.

Multi-stage tube-regulated power supply circuit feeds power to different amplification stages independently. It can minimize ripple effect, eliminate circuit interference, and enhance circuit performance of both the voltage and current amplification.

The separated high-rigidity chassis and damping mounts absorb shock and vibrations effectively, isolating noise interference caused by transformer vibrations and magnetic leakage to achieve a higher SNR.
