Sony SB-V1000 Video/Audio selector unit.  Very cool unit with front audio level meter.  I used it to switch between multiple CD players.  However, at least one of the inputs didn't work and maybe at least one of the output channels didn't work.  I was able to use it as it is but I found another one fully functional so selling this one STRICTLY AS-IS, FOR PARTS, NOT WORKING.  NO RETURNS, NO REFUNDS.  See my 100% positive feedback... Thanks!
