42-355 field coil gets very warm
#11

Randal,

Yes, sometimes its the simple things we forget to apply, like ohms law. Recently, I was restoring a Stewart Warner 950 radio and the ballast was open. After opening the ballast, I determined that it was nothing more than a power resistor wound using nichrome wire on a ceramic form. But where to get nichrome wire these days? One of the guys on another forum mentioned that a number of sizes of nichrome wire with their ohm/ft rating was available from AES. I bought the nichrome and rewound the ballast and it worked well. As you say though, it does throw a lot of heat. These forums are really great because they are so filled with knowlegeable and friendly people who are willing to help. Now, if I could only get spell checker on these pages, lol! Maybe I should compose my reply in Microsoft Word and then paste them into these pages.

Regards,

Ed
