Hi,   
      
   The supply in this photo powers an incandescent bulb of a Zeiss   
   microscpe.    http://easthope.ca/ZeissLampSupplyLPS7.5.jpg   
      
   That supply accepts 110 V input.  The bulb is marked 6 V 15 W.  For   
   several decades, the 'scope was commoplace in North America.  Likely a   
   similar supply accepting 220 V input was common outside North   
   America.   
      
   I want to find a power adapter which accepts 220 V input. eBay has   
   this and similar listings.    https://www.ebay.ca/itm/185935059631   
      
   If the output connection is compatible with the plug on the lamp cord,   
   the supply should work but the total price is approximately 670   
   Canadian dollars.  =8~/  Rather pricey to power a small bulb.   
      
   A simple alternative is a 6 V brick adapter and potentiometer.   
      
   Other ideas?   
      
   Thanks,                             ... Peter E.
