Nixie tubes are cold cathode gas discharge tubes with multiple elements. Elements are typically in the shape of numbers from 0=9, or mathematical symbols. Elements glow orange when high voltage is applied between the anode and one of the cathodes.

Anode scanning Nixie circuit
The 75v rail is a function of the limitations of the BSX21 transistor, which has a max 80v VCEO specification. When that circuit was produced, low cost high voltage NPNs were not available. These days …

Can you place two boost converters in series to boost 3v to 180v?
A single stage boost converter from 3v to 180v would be very challenging, too large a ratio for the compromise design of the boost inductor.
However, a single stage flyback would be straightforward. …

What are some ways to improve a voltage multiplier?
You need to ditch Rd from your first schematic, and use a low impedance push-pull output as in your second schematic. However, as you correctly say, 36v will toast the gates of 20v Vgs FETs. There are …
