   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.   
      
   I believe it was just used as a power supply.  Some years ago I got some   
   interface hardware that was associated with a PDP8.  Inside the hardware box   
   was a card with BB 501.  I liberated the 501 and used it in my poor mans   
   triple mode PS, alongside my    
   5VDC open frame PS.  I disconnected the interface box from the PDP8 and got it   
   running without any issues.
