Most Philco voltage tables were measured with only a 1000 ohms per volt volt meter, which loads circuits down (your resistor). Also AC
line voltage was usually specified at 110-115 VAC.
That's why I use a variac on the AC line and a 100 ohms-per-volt DC voltmeter and not a VTVM or a newer hi-Z multimeter.
Many times this is written out and specified right on the Philco Service Bulletins in the aligment section.
