 From this, I guess you made a mistake connecting all in parallel 
(because of this, the neon bulb acted like a "gas discharger" and blow 
itself because it had no current limitation); instead, the 12 Meg 
resistor must be connected in series between rectified line voltage and 
paralleled capacitors with neon bulb.
