Jay,



The spark gap is mostly overheating during operation.

Try letting a fan blow across the gap to keep it cool.

It should help a lot.? A better spark gap may be helpful

depending on the present design.

Subject: Why is the coil being weird????

I have been tinkering with my coil for a while now and it has been acting weird 
since the day I built it.  but it is just starting to get on my nerves.

So basically
When I run my coil at first if is good.  producing 30" sparks lots of noise etc.  

But after about 5-6 seconds it just craps out.  The spark gap stops making the 
normal loud spark gap sounds and it starts to make a really quick softer sound.   
Like the one the tv makes when there is no channel and just static.  At the same 
time the sparks length drops to about 4".   
I turn it off.  let it chill for like 30 seconds and then it does the same 
thing.   If I turn it off and don't let it chill it just does it quicker. 
Very annoying.  
I am currently using 5 obits in parallel and 2    .005uf home made capacitors.  
The spark gap is 2 bolts less than 1/4" apart in a tube that is connected to the 
blowing end of a vacuum.  The frequency is about 600kHz.  
Any ideas and  help will be great.

Many thanks,
Jay Howson
