ilanode,

Whoops sorry for the Ingo mix-up, I actually meant to ask 
selfoscillate to pop out his module, but either way.....  I thought 
perhaps since there was already the electrolytic on top it would do 
the polarity work and any old 100uF could be slapped on the bottom. I 
guess that probably wouldn't work now that I think about it...  I've 
got some spare parts here from other DIY projects and just don't want 
to go out for a component I don't need.  I may have one anyway, I'll 
have to check and if so I'll go ahead and do it, do it.  Thanks for 
the input.  

Anyone else considering this mod as DIY, make sure the cap is rated 
at 16V or more!

Cheers,

Nick Keller
