I’ve tested through AUX and headphone jack. Sound is clear in both channels. Pots need to be cleaned. This is unrestored in original condition. Left side of glass is cracked as shown in photos.

Vintage McIntosh MA5100 integrated amplifier. Unit powers on and functions properly. Classic McIntosh sound with solid-state reliability. Green illumination present.

Please note: front glass has a visible crack near the volume control (see photos), and the original wood cabinet shows corner wear consistent with age. No recent servicing history.

Sold as-is due to vintage nature. Carefully packed and shipped.
