RE: Re[TCML] NST rebuild good
Thank you Sir.
I am starting to get a "better grip" on it.
I really appreciate the feedback that I get.
If I go back to the original post, you're using a .033uF cap with a
rebuilt and deshunted 15/120 NST and a 120BPS sync RSG. The problem is
that the capacitor is much too small for this configuration, resulting in
the cap charging to a too-high voltage and self destruction and safety gap
firing. With a static gap, if the cap is too small, the only consequence
is that the gap fires more often but at a safe voltage determined by the
gap width. With a SRSG, the cap is free to charge as high as it cares to;
it's up to you to choose a value that limits it to a safe voltage. With
my 15/60 NST and SRSG, I've found that a .04uF cap is optimum, so you
could go at least 2-3X larger and maybe more considering the deshunting.
