I just got a GE radio with a ballast tube. I've never seen one(or heard of one) and was wondering how to test it.
I did some reading about it but couldn't find a test procedure. Any ideas?
Thanks,

What's the number of the ballast?

You simply measure resistance between the pins where the resistors inside the tube are connected to.
It is that simple.

These ballasts are available from several sources for about $12. Looking at the schematic, I see that pin 3 to pin 7 should show continuity. Pin 7 to pin 8 is the dial lamp connection. To check both sections check from pin 3 to pin 8, then from pin 8 to pin 7

Well, you were right. No continuity at all. I opened it up just to see what it looked like and found broken wires inside. Has anyone put resistors inside the metal tube instead of replacing it?

| Renovated Radios do carry what you need.
As for the voltage, a wire should be at least 300V-rated.morzh — 11:13 PM |
