Secondary Coupling
cc: tesla-at-grendel.objinc-dot-com
Richard,
I had four pieces of plastic made 1.0" thick and 8.0" in dia. I placed all
four under the secondary to raise it up and loosen the coupling. This seems
to have eliminated all the corona problems - I don't see any. I think I did
loose some intensity in the secondary discharges. I will try it again with
only three discs (3.0" elevation). This shouldn't make it necessary to
retune the system - correct?
I did notice a new problem and I'm not sure what it is. As I turn the power
up, the gaps start firing and before breakout I hear a muffled pop sort of
noise (my wife calls it a "poof sound"), kind of like a small muffled
explosion. It sounds like I might have discharges inside the secondary coil
form. It is sealed, the wire never goes inside and I have a small hole in
the center in the botttom plate to equalize air pressure. Maybe it is
comming from the rotary spark gap, it is in a box which could account for the
muffled sound. I also hear this sound sometimes when I am getting discharges
from the toroid - at full power. I need to find this, it sounds like
something is going to get damaged.
Can we talk about toroid height again? I realize the correct height for a
particular system must be found empirically. What symptoms would I see if it
is too low? If it is too high?
By the way, I am now using a new H.P. VL2 486/66 computer instead of my old
Macintosh. Now I will be able to use all the DOS utilities that everyone
else uses for uuencode and for GIF files. Also I can read the disc that you
sent me.
Thanks, Ed Sonderman
