The oscillator coil. Still no knobs either. Time to break out the #36 wire and have some fun! This one is an earlier version. Less louvers on the top of the cabinet and no ridges on the tuning cap for the pointer.

At this rate, you're going to become an expert on the 600!
Well I guess that will be my big claim to fame!! I think I already know too much about them.The dollar pocket watches seems the be a nice reprieve from radios and the like. Anyway my daily watcher B/W TV when up in smoke the other night. It went ZORCH and the screen went black. After taking a good look at it the filament winding for the damp tube arced over to the chaiss. Lots of HV on it. So it's getting it's own transformer. Maybe today.
