Yamaha - AX-400 & TX-400 Stereo set - Multiple models

The Yamaha AX-400 stereo amplifier and TX-400 AM/FM tuner form a matching audio set from Yamaha's Natural Sound series (late 1980s approx.), both finished in silver.
The AX-400 is known for Yamaha's characteristic Natural Sound philosophy: a neutral, uncolored reproduction with an open sound character. The amplifier features a variable Loudness control (allowing you to tailor the contour precisely to the listening level), a CD Direct switch for bypassing unnecessary tone circuits, and an integrated phonostage that is switchable for both MM and MC cartridges. The matching TX-400 tuner is known for stable digital tuning and clear reception on both FM and AM with a memory for preferred stations.
The set is supplied as a power amp and tuner together.
Condition-wise, both units are in neat condition with normal signs of use consistent with their age. Both units have been tested and work.
