First off, you should NEVER post a binary into a text ONLY usenet group.
Ok.... on to the supply section.
I see a multiplier after the transformer. That means the raw output of the transformer is 3400 volts divided by two, PLUS the diode drops.
The bottom resistor under the 100 Meg Ohm resistor is your metering take off. The meter is in the wrong place from what I can see. It should be across the bottom resistor, and the lower leg of that resistor should ALWAAY be tied to ground.
What you should get with a ten megohm DVM is likely one volt per kV. The HV 100M resistor, and the "bottom" resistor under it act as a voltage probe for safe voltage readings. The line under that resistor should always be grounded or it "float high". This is a very bad thing as it can damage your meter. The other little RC circuit. The pot appears to be the calibration resistor for the metering tap (probe point). So, tie those two "meter" nodes together, and move the meter up such that it is across the bottom, low value resistor in the voltage divider there. One node is the junction to the 100M, and the other ground, or right there at the bottom of that lower resistor. Do NOT leave that line as an open line (between the meter nodes). That is the only thing that appears to be wrong.
You need a real HV probe so that you can not only determine what it does put out, you can calibrate the metering stage of the circuit as well.
The low volt cap, and two diodes either got diagramed in wrong, or appear to me to have no function. The 10k resistor in series with the output is very likely a 1/2 watt carbon composition resistor, which is used in HV circuits as "arc suppression" resistors. They can also limit current.
Future diagram posts should be made to a binary group and referred to here, such as alt.binaries.schematics.electronic OR alt.binaries.pictures.misc NOT here.
I hope this helps.
