Altec Coke Bottle Mic PSU

Posted in Repaired with tags , , , , , , on November 28, 2012 by AnalogAudioRepair

A client sent me a vintage Altec M11 “Coke Bottle” tube microphone that needed re-capping.  The 518A power supply has a lot of caps, but the new ones are much smaller.  After re-capping and a new tube the mic sounds great!
