<< Ed,
 
 You can also tell if the gap is firing at 120 or 240 bps by the
 sound.  The 240 bps will give twice the pitch.  Of course you'll
 only be able to compare once you've achieved each break-rate,
 but I thought I'd mention it.  With the larger cap you're using now,
 it will be impossible to keep the NST voltage output low at 120 
 bps due to resonance, thus the safety gaps will fire.  At 240 bps
 it should be OK.  At 120 bps, you'll need to widen the safety
 gaps more than they were using the small 0.008uF cap.  LOw
 (120 bps) break rates are more efficient in an optimized system.
 For 120 bps, an LTR sized cap of about 0.024uF  or  0.028uF would
 keep the NST voltage and cap voltage lower, so that may be better.
 I always run LTR (with NST's) now at 120 bps.

John,

I will try 120 bps this weekend, with a .032 ufd Maxwell cap that I bought 
from Jason Zuberer.
