These voltages can kill you...
keep your hands OUT!

Here's the wiring for the transformer we found. Of course your filter cap will be different but this gives you an idea of what is what. With 240 volts applied to the input as wired below the output should be approximately 3,712 volts DC (1.414 * 2625 VAC on the high voltage windings). The meter multiplier is integrated into the bleeder resistor string as shown below.

Capacitor C1 is your choice for the filter cap. Resistors R1 through R50 are all 10k, 2w metal film resistors. R51 and R52 make up a small shunt which will determine the range of meter M1, limited by the pot, R53. For a 1 ma meter, R51 and R52 should be 1k and R53 will provide 1 ma through M1 at about mid range. For a 50 ua meter, R51/R52 should be somewhere around 50 ohms each. Fuse F1 should be 1 amp or greater. Resistor R54 is the HV safety resistor (glitch resistor) and should be around 50 ohms at 50 watts (a pair of 30 ohm, 50 watt resistors in series should work nicely).

The RD/BN and BL/YL windings can be placed in series with the BN/BK and YL/OR windings to lower the output voltage (original wiring for 120 or 240 volts). The wiring shown is the original wiring for 100 or 200 volts. The VL/VL winding provides 6.3 VAC.

These pictures were taken of my Simpson 260 set on AC, 1000 volts with the 5000 volt multiplier. The input voltage was 120 volts applied on the OR/YL winding.

This is the output of the YL/RD winding (2575 volts AC).
This is the output of the OR/BL winding (2625 volts AC).
