Ok, giving this 46-1209 transformer one more attempt. Since my last post, I've replaced the caps (including Bakelite block and electrolytics) and power cord.
The 40-watt bulb on the dim bulb tester—I made one!—glows faintly, which I understand is a good sign. I also opened up the transformer and, while it ain't pretty, nothing appears obviously damaged.
Primary white to white: 0.4 ohms, like last time. (Stupid decimal point.) Am I checking at the right connection points? Please see orange arrows in photo.
Rectifier yellow to yellow (pins 4 & 6, tube taken out): 184 ohms, like last time.
Power cord prong to prong (radio switched on but unplugged): 50 ohms. Don't know how to interpret that.
Are there other basic checks I can try before I give up and ship this thing off to more able hands?
