    Early Mcintosh MC250 restoration

    Hi everyone! I recently found a great deal on an MC250 poweramp with an MX110z preamp. My initial plan was to restore the MX110z first but unfortunately it was very badly damaged in shipping (broken glass, broken tip of the power knob, broken panloc button, etc) so I've decided to start with the...

    I recently scored a turntable from goodwill for really cheap. Everything works- the turntable, radio, and speaker are loud!

Needless to say they looked pretty rough but I felt they might be worth a gamble for 100 bucks. In fact “rough” might be a slight understatement, they appear as though they...
