No problem. LTR is simply to use a cap that is larger than the cap size 
that would be resonant with the transformer. This is mainly to save 
NST's in particular which just can't handle much voltage stress and also 
helps to save caps. For static gaps, the typical value is 1.5 x resonant 
cap size. For SRSG's, about 2.3 x resonant cap size. You should take a 
few minutes and read up on resonant charging at Richie Burnetts web 
site. Richie has put together some graphs which are very helpful.

It's wise to use what you have. I was mainly looking at optimizing the 
top terminal. This is something you can do later on if desired.

Take care,
