I went down and took some measurements.

6.3V is reading 6.54V.
5V is reading 5.13V.

I could not measure plate to plate on the rectifier as one of the electrolytic capacitors is in the way, so:

5Y3GT pin 6 to B- is reading 288.8 VAC.

B+ measured 325.3 VDC from rectifier output to B-; and 248.4 VDC from rectifier output to chassis ground.

This transformer has three terminals for AC input - common, 115 and 125. I am using the common and 125V taps. At least, that is what the diagram states (gray, 115V tap; black, 125V tap). I should measure with my ohmmeter (with the power off and radio unplugged, of course) to be sure I am using the 125V tap and not the 115V tap.

AC line input is reading 123.9V.

Using a 5Y3GT, I only needed 2A for the 5V winding. And using LEDs for the three pilot lamps will cut down on current consumption a little bit.
