The **Adcom GTP-400** is a stereo tuner-preamplifier introduced in the late 1980s, combining preamp functionality with AM/FM tuning in a clean and minimalist package. It features a moving-magnet (MM) phono stage, multiple line-level inputs, and straightforward tone and balance controls. Known for its quiet operation and neutral sound, the GTP-400 was appreciated by audiophiles who wanted reliable performance without unnecessary frills, making it a solid companion to Adcom’s power amplifiers of the same era.

The **Adcom GFA-545 II** is a two-channel solid-state power amplifier designed to provide stable, high-current output for a wide range of loudspeakers. It delivers around **100 watts per channel into 8 ohms** and **150 watts per channel into 4 ohms**, with very low distortion and excellent control due to its high damping factor. Built with robust construction, it measures roughly **432 × 127 × 279 mm** and weighs about **11 kg**, making it a compact yet powerful amplifier that pairs seamlessly with preamps like the GTP-400 for a well-rounded hi-fi system.
