   >I'm going through some stuff I have to move (retiring in June) and trying to   
   decide what to keep.  I have a Burr Brown 501 dual supply that puts out +/-15   
   volts with 115 VAC in.  The supply is working but I don't know what's its use   
   was originally.  It'   
   s a compact block and it's heavy, but there's no current rating listed and I   
   haven't been able to find out anything about it.  Is it supposed to supply a   
   reference for calibrating meters or is it used as a power supply?  Not being   
   adjustable I wonder if    
   it's made for something specific.  Any insight appreciated.   
      
      
   It's just a supply aimed at permanent installation   
   in analog circuits.   
      
   If it's got air holes, (or you can crack the case)   
   you might see an internal preset pot or two -   
   one to adjust output (11-16V)   
   and one for balance -   
   sometimes a current limit adjustment.   
      
   It might have some value as an antique.
