Art,
I know what you mean by using a magnyfying glass.. I have to use one all the time
Cap 27 is the 8 ufd which ties to the two resistors near the XXL tubes and the negative to ground. Cap 27A is the 16 ufd tied to the ouput DC side of the field coil and is located on the schematic just to the right of the power supply and field coil. The NA site shows this on the 41-280 (code 121) schemo which is a Riders Vol. 12, Philco page 63.
Below the 16ufd value is a circle with the # 27A within it. It shows typically ~ 180VDC across this cap. The negative of 27A does go to ground.
The negative of the #62 cap, as Ron said, goes to the center tap of the high voltage transformer secondary winding.
