New variant lighters for gas [ 1 ], as shown, has the best features. Her scheme is less critical to the selection of elements, in particular, diode VD3.
The oscillation frequency is determined by capacitor C2, is reduced. Excluded hot detail - resistor R1.
The VD3 diode can be replaced by D, D. The transformer T1 has the same winding data as in the previous design, but there is a difference: in the hole of the coil, you need to insert 10-20 PCs plates permalloy transformer or steel, of a width of 4-5 mm to the length of the coil. You can also install the ferrite core from the contours LW, ST, FC, or SAT with a magnetic permeability 400-2000. If the secondary winding of T1 winding wire PELSHO of 0.09, the number of sections from three can be reduced to one or two.
