    Hi. I am about to assemble my (Dumble) Tweedle Dee Deluxe build, and I have a pilot light as on the picture. pilot lights with It's called a Midget-flanged neon bulb 240v.
    Metal body with red plastic lens.
    The neon bulbs require additional ballast resistor connected in series, 220k. Any suggestion on how to set that up?

    That looks dangerous as the insulation between the poles and case don't seem very good. Does your neon lamp holder have any safety certification?
    To be safe, I would use two 100k 1/4W Carbon Film or Metal Oxide resistors, one on each leg and connect them to the required AC source, preferably on the secondary of your mains transformer.

    I would fit a 6volt 150mA incandescent pilot light off the heater voltage, if up to me.
