Microphone is in perfect working condition!!  I'm selling because I simple don't get to use it as much as I'd like.  Tube is working great.  The microphone is in mint condition, no dents, dings or scratches to be found.  You might find a faint scuff or two if you really examined closely.  The power supply does have some scratching on the top from usage.  The case also has scuffing on the exterior.  Everything about this kit works flawlessly and I can attest that the sound quality is as spot on as the day it was made.
