50k 5 gang potentiometer

bourns has a data sheet for one but finding it in stock is a whole different ball game... http://www.bourns.com/data/global/pdfs/PTD90.pdf

you might be able to find a 3 or 4 gang and take it apart and build a 5gang using parts from 2 smaller multi gang part numbers but that might be more hassle than its worth. Thats the route I've taken when I've replaced one that I couldn't find in stock...
