Sorry, I didn't mean to be secretive.  My 15/60 is also a Jefferson.  I initially cursed it when I found that I couldn't remove shunts, but all is since forgiven.

What happened when you tried .04uF with just your 15/60?  I would guess that the worst that would happen would be just a lower than optimal bang voltage.  But then odd stuff may happen when the cap to too much LTR...

I don't have a numerical answer, but I would guess not a lot, as I spent a fair bit of time determining that my 200uF of PCF caps was pretty much optimal.
