See any you like?

Thanks for all of the replays. I don't think anyof those coils will work I have tried to replicate the device with many similar common rf cores but they have not worked. As of now a identical coil is needed.I will keep searching for one with the links given. Later today I will upload a videos of the replicas I have tried to make.

Well, you are right about one thing: It doesn't work as a JT with a coil selected from that group. I can get a very dim light... but only with the
capacitor disconnected and my finger touching several places in the circuit. 2n2222a and BC337-25 transistors work the same, or rather, don't
work equally, for me in my build of this circuit. I used one that looks like it has the right number of turns and the right thickness of wire.

However those type coils _do_ work just fine in the "basic" JT circuit, when the "dots" of the windings are connected correctly. I would be very
surprised if suddenly a different 1:1 ratio common-mode choke would cause this circuit to "work" as a proper JT with a nice bright light.

Try shorting the electrolytic capacitor.

Hi TheGeneralHackr,

From replication point of view, there are some 'issues' with this circuit shown
in the schematic of Reply #3 above.

With the primary battery of 1.5 V there may not be a sufficient base current to open
the 2N2222A transistor at the startup via the 470 uF capacitor (unless the transistor has
a very high DC gain, h_FE ) because the 3 V LED may have too high DC resistance (unless
you test several LEDs or use the LED from the dimly working prototype circuit for replication)
to let an appropiate collector current flow for starting up oscillation, even if the winding sense of the coils
would just let this happen.

Besides the issues of the transistor hFE and the LED forward conduction capability at 1.5 V, you may wish
to discharge the 470 uF capacitor before any new startup attempt when you change a component or
coil winding sense or whatever because any residual, leftover charge this capacitor may have it would work against
the 1.5 V battery voltage, rendering the chance for startup even less likely at the difference of the two voltages.

Anyway what I mean is there are no two (or more) identical coils, it is unlikely that solely the coils are critical
in this circuit. And the base current for the transistor is indefinite "by default" via the electrolytic capacitor: try to
connect a 1 MegOhm (or some hundred kOhm)  resistor in parallel with that capacitor to see what its effect may be like in helping startup.

EDIT: try to use a red or green LED instead of the white one, these have a forward voltage of 1.6 to 1.9V or so and see
how the circuit works with them.
