Yamaha M-50 stereo power amplifier. Vintage amp from the 1980s. Very nice and warm sound. All lights and VU meters work. Replaced bulbs with LEDs.

• 120 watts per channel into 8Ω (stereo)
• Frequency Response: 1Hz to 100kHz
• Total Harmonic Distortion (THD): 0.0005% – 0.002%
• Damping Factor: 200
• Signal-to-Noise Ratio: 122 dB
• Dimensions: 17 x 15 x 5 inches
• Weight: 26 lbs

• Good cosmetic condition
• All lights work as they should
• Dual digital power meters
• A/B speaker switch functions, however the B speaker outputs do not appear to work. It could be something simple but I haven’t investigated it.

Sounds wonderful, powerful, and smooth.
Preamplifier is required.
