Hi guys, I’m selling my vintage Yamaha MA-10 mini amplifier / headphone amp made in Japan in 1982!

This compact Yamaha unit has been fully tested using a compatible power supply (not included in the sale). It powers on and works very well overall, with clean sound and all main functions operating correctly.

Please note:

• the bass control knob does not seem to produce any audible change

• the amplifier should also work with batteries, but I have not tested battery operation

Aside from the bass knob issue, everything else appears to function properly!

Because of this known issue, I am selling it at a discounted price, strictly as-is, with no returns or refunds.

Technical info:

• Vintage Yamaha MA-10 mini amp / headphone amplifier

• Compact portable design

• Headphone output

• Tone controls

• Volume control

• Designed for guitars, keyboards, small audio devices and personal monitoring

• Can operate via external power supply (not included)

Cosmetic conditions are very good for its age, with normal vintage signs of use. Please check all photos carefully before purchasing.

Feel free to contact me for any additional information.
