RE: secondary jack (resend)

["Lau, Gary" <Gary.Lau-at-compaq-dot-com> (by way of Terry Fritz <twftesla-at-uswest-dot-net>)]

Unless the jacks are located within the "protective" confines of the toroid
(i.e. above the lowermost part of the toroid), the bumps of the jacks are
likely to promote corona.  I would recommend splicing the secondary magnet
wire with the smallest possible solder bump to a piece of less-fragile thin
stranded wire, and space-winding that up to the toroid.  The banana jacks
can be used to connect the stranded wire to the inner equator of the toroid,
as corona won't form there.

		     Folks,
		     
		     For attaching my secondary to the toroid right now I
have a couple 
		     extra turns of magnet wire loose on the top of the
secondary.  I 
		     "spacewind" this up and tape the end of it to the
bottom of my toroid.
		     
		     This method is clumsy, fragile, and it makes me nervous
to put stress 
		     on the fragile magnet wire.  I have had the tape come
loose while I 
		     was running the coil. (scary!)
		     
		     What I would like to do is cut the magnet wire close to
where it comes 
		     loose from the secondary.  I want to solder a female
bannana jack to 
		     the end of the magnetwire, and epoxy it firmly to the
secondary on the 
		     top rim of the seconary..  Then, I can solder a male
banana jack to a 
		     piece of ordinary wire and bolt the other end of the
wire to the 
		     toroid.  
		     
		     This way no stress gets placed on the magnet wire, and
the regular 
		     wire connecting the toroid to the jack is easily
replaced if ever 
		     necessary.  And it will be more secure and professional
than my 
		     current lame tape method.
		     
		     Does anyone see any potential problems with this?
		     
		     thanks,
