Jorge, the 16 V rated capacitors sound low voltage rating for me, question is which part of the circuit you intend to use them?  (Remember the unloaded 66 V output DC voltage.) 

One more note:  be careful with the LED bulbs because they may not be able to absorb the too high voltage BEMF spikes like the neon bulbs do.   
Look for the manufacturer data sheet for the LED bulbs, perhaps it turns out how much overvoltage they are able to survive, depends on their internal circuitry. 
Google search with the make and the type of the LED bulbs may reveal such data sheet or internal circuitry.  All I mean is do not trust too much in their high voltage protection capability.

yes, I understand, I already have more than five months with the same led bulb and it is still intact but with 12 volts, I don't know if with 24 volts it is the same, maybe it burns .....
I am doing more experiments and instead of the LED lamp I placed a 2.2 K resistance in the BEMF and also two neon bulbs in parallel and everything worked very well, I don't know what you think, what will happen with 24 volts?

The BEMF may be higher at the 24 V input, so perhaps start with only 15 or 18 V DC input first and experience how the LED brightness changes.   

Maybe connect a current limiting resistor of say 1 kOhm in series with each LED bulb to limit its current and see the brightness: if is not too excessive yet at  say 18 V DC input, then just short out the series resistor with a 100 Ohm and see the brightness too. 

To protect the transistors, perhaps connect two neon bulbs in series (not parallel) with each other,  this adds up their breakdown threshold voltages and will limit the spikes to 2x 90 V for the collector-emitter of the npn transistor.  MAybe this protection is not strictly needed. 

Good luck.

In this video you can see very well the high voltage peaks that are generated in these circuits and this inprovised motor that I have at home, the led bulbs are really very good since they support these voltage peaks very well, I am applying only 12 volts in this experiment.
