DS Audio TB-100 Tube phono equalizer. A new era of analog experience DS Audio, December 3, 2024

We are excited to announce the release of DS Audio’s first-ever vacuum tube phono equalizer. Experience a new era of analog audio reproduction created by the synergy of optical cartridges and vacuum tubes.

Product Features

Pure Vacuum Tube Amplifier

The TB-100 features quad-matched ECC82 (12AU7) tubes, carefully selected specifically for this product. Using our in-house proprietary tools, we ensure variations in tube performance are limited to within 1% (0.1 dB), delivering optimal performance. Each channel houses an inner tube for voltage amplification and an outer tube for the output buffer, achieving a rich and transparent sound. The design incorporates a simple two-stage amplification process with low-impedance cathode follower output stages, resulting in pure and dynamic audio performance.

Wide-Bandwidth Transformer Input

Audio signals from the PD are converted from current to voltage, enabling precise phase alignment between left and right channels. This design ensures flat frequency characteristics within -1 dB across a wide range from 10 Hz to 70 kHz, delivering clear and high-quality sound.

Dual Mono Construction

The TB-100 employs a symmetrical dual-mono amplifier structure with completely independent ground and power transformers for each channel. This eliminates cross-talk and interference between channels, allowing you to enjoy a clearer and richer soundstage.

Low-Noise, Low-Voltage Power Supply

Equipped with a low-noise regulated power supply dedicated to LED power and PD negative bias voltage. Separate power circuits and transformers are used for each PD channel, further enhancing the stability of the voltage supplied to the cartridge.

Specifications:

  • Rated Output Voltage: 500 mV (1 kHz)
  • Input Terminals: RCA connectors
  • Output Terminals: RCA connectors
  • Output Impedance: Approximately 700Ω
  • Dimensions: W44 cm / H15 cm / D48.2 cm (including connectors)
  • Weight: 18.7 kg
