Condition: For Parts or Not Working
This used power amplifier powers on and both channels output sound but doesn't appear to amplify anything by a significant amount. Both channels output the same level. Different inputs tested and all the same results. Based on this, we are selling it in "as-is" condition. Please view our photo set and contact us if you have any questions.
