More info on the tesla coil lamp ignighter.

Ive traced out the circuit and continuity tested the tesla transformer.

RF supression capacitors across both supplies.   DC/AC (50Hz) resistance
of secondary is 0.1 Ohms.

SG is 1/8"
Pri Cap - unmaked

Tesla coil makes ideal lamp ignighter as at RF resonant frequency very high
voltages can be presented to the lamp whilst keeping the DC resistance
low for high current delivery once the lamp is alight.
