Re: [TCML] Problems with secondary - internal arcing



Hi Alan, Steve,

For what it's worth, it's good practice to run the wires up along the outside of the form. It wouldn't hurt to maybe glue in a baffle inside the secondary a couple of inches down if your going to continue to run the wires inside the form.

These days I run the wire up the side of the form and attach the wire on the top cap, but in the past I ran it inside as well. There have been a few that found similar problems doing that, so I changed my practice. I also coat clear epoxy on the inside of the of the cap where the bolt head is to help keep it in place (while adding/removing top load) and to also provide encasing.

Greetings Everyone
As the guy who wound this secondary, and provided Steve with the parts that
he is using, thanks for helping him with your ideas ( except for the fellow
who said I should be shot, lol). The secondary was coated with Dolph's AC-43
and is 24 awg HAPT magnet wire. I have had over 100 folks complete this
package with great results. Things that are obvious to many of us (like
keeping the magnet wires to the top load and RF ground as short as
possible)are easily missed by new comers to this great hobby. I will make
sure I add this note to the tip sheet I include with the secondary. I have
had no internal arching issues and when tuned with a 12/30 transformer arcs
are about 2ft with a single tungsten static gap.
