About the GTP-400

The Adcom GTP-400 is a high-performance tuner/preamplifier that separates low-current preamp circuitry from high-current power amps for superior sonic quality. Produced around 1988-1989 with some sources noting 1996, it features proprietary Class A linear-gain amplifiers, precise RIAA equalization for MM phono cartridges, feedback tone controls, separate recording selector, and compatibility with Adcom GFA-535 (60W/ch), GFA-545 (100W/ch), GFA-555 (200W/ch), or bridged mono setups up to 600W/ch. Inputs include phono, tuner, tape 1, tape 2/video, CD; controls for volume, balance, bass, treble, contour, mono, mute. Noted for excellent dynamics, bass control, low noise, though tuner section may have alignment issues in some units. MSRP was $400; now a vintage collectible.
