[R-390] E209 Test Point Voltage Is Low

I've been doing some tube-pin and test-point voltage checking. According to
the manual, E209 should have approximately -6.8V. I'm getting approximately
1/10 of that or less.
Looking at V202 (1st mixer), the manual calls for -0.4V on pin 6. I'm
getting a voltage pretty close to that -- approximately -0.5V. Pin 6 is
connected to E209 via R208, a 27-ohm resistor. How can it be that E209
should have such a larger voltage than pin 6 considering the only thing
between them is R208?
Thanks,
