Yes, the voltages on the schematic are DC using a voltmeter with a high input resistance quoted on the schematic as 122 megohms. The voltage using a modern DMM with an input resistance of 10 megohms or so should be pretty similar.? Is the 200CD producing any output and does this vary with the coarse frequency range switch? Assuming the mains voltage is correct, the higher voltage at the junction of R27/28 and reduced voltage drop across L6 suggests no current draw by the oscillator circuitry. You could check that by measuring the voltages across R27 and R28 which should be about 30 volts each. If it is much lower than that or even zero you should check all the tubes by substitution if possible. Also check R40.
The output voltage into 600 ohms at the maximum output setting should be 11.5 volts AC.
Good luck!
