The DS Audio TB-100 Tube Phono Equalizer is a dedicated all-tube phono equalizer designed for DS Audio optical phono cartridges. It uses carefully selected, quad-matched ECC82 (12AU7) tubes, a two-stage amplification circuit, low-impedance cathode follower output stages, and a symmetric twin-mono layout with separate grounds and power transformers for each channel. DS Audio describes it as delivering a rich, transparent, dynamic presentation with a wideband transformer input and a claimed flat response from 10 Hz to 70 kHz within -1 dB.
