Hi gyulasun, had to run out after realzing the arrow was wrong way, hehe, thanks gyula, it's fixed now.
I will test the puffer capacitor tonight.

Edit: Hi gyulasun, i placed a 450 volt - 68 uF polarized capacitor across av plug output.
The led bulb went out until the capacitor filled up, then the voltage across bulb (brightness) did not go up or down from 117.8 volts dc output.
Of course, I'm using a different primary now, 40 turns of 24awg. magnet wire and input is only 20 milliamps at 5.14 volts or 103 milliwatts and brightness is still darn good for that input.
Of course, zero heat in the transistor as well.

Thanks Skywatcher for the info and update on that neat Slayer Exciter you made.  Slider I worked most of the day on making a simple voltage booster for my crystal oscillator exciter.  I just connected it from the tunable inductor on the exciter into the base of an MPSA06 NPN via a cap. The bare bones 'amp' was just an led connected to a 3v source and the collector.  The emitter went to the (-).  The crystal oscillator had enough punch to trigger the transistor and light the led.  Nothing fancy but it proved the concept.

Hi all, Hi lidmotor, it is one of those filament style led bulbs from Feit.
Though I can't seem to find the exact version i bought awhile ago, a 2 pack of 40 watt equivalent.
It is printed on the bulb, 3.6 watt input at 450 lumens, this link is similar, https://www.homedepot.com/p/Feit-Electric-40-Watt-Equivalent-A15-Dimmable-Filament-LED-90-CRI-Clear-Glass-Light-Bulb-Soft-White-2-Pack-BPA1540927CAFIL-2-RP/304112237
,though it uses more power.
I would say, most of these filament style will work well, since I think they use a higher voltage without the circuitry.
It's not too difficult to remove the small circuit board from bottom of these bulbs, though i may have used a heat gun to loosen the glue holding base to glass bulb.
Hi erfandl, here is the circuit drawing.

Edit: just checked the 24awg, magnet wire primary turns, 19 turns, wrapped together tight, though is not tight on top of other coil.
Going to make a tighter wind primary with double the turns, 40 turns and compare, then can remove turns and compare also.

thanks for reply. so primary is 19 turns and secondary is 40 turns ?

Hi all, thanks for the kind words lidmotor.
Hi erfandl, the original primary turns are 19, though the 30 awg. magnet wire secondary is one full layer over the 3-1/2" core former, I didn't count secondary turns.
Also, the primary is taped tight on at least  two sides, to get the wire strands tighter together and still allow the primary coil to slide on top of the secondary for tuning.
