Donald L Smith Device

The 2 secondary coils config is something Ive wondered about.  Looking at Dons pictures of it, it seems hard to tell if the secondaries are wound opposite directions or wound in the same direction all the way across. even looking at the supposed originals of the circuit, there is a  possibility that the 2 halves of the secondary are oppositely wound.
This was a while back. But remember what I thought back then.

Thats interesting Where did you see that? As Don shows in one of his videos a commercial device where he comments on how its made or altered
he has a long wound coil he counts 4 Turns then removes 2 0r 3 turns then counts another 12 turns and another gap with removed  or 3 turns and then
another 12 turns is counted end of coil modification, I see no way the one 12 turn coil is reversed in his device. However, if winding your own coil then anything goes as long as you keep the phase the correct orientation. 

One thing though the GDT shown by one builder is not suitable at all (it's a regulator, not a spark gap it won't be of any use here that's for sure if indeedy deedy the device actually works, experiment yourself don't just sit speculating.

This is going back a good way but still!  There are a lot of deliberate mistakes in it and as is I can't see anything happening if made up!

What cap value are you charging up doing into the first coil Coil  0.47 at 160,000 WTF no way you're after a spike, not pure DC and whats a neon regulator doing in the circuit? unless the gas has been let out and the electrodes ore
adjustable get a real spark gap. Oh and get a scope and tune it with an EHT loop.
And if i were you I would use some bleeders across the caps before you kill your self with possibly some high luminosity low current LEDs so you can see it's on and generating high voltage don't forget some reverse voltage diodes as well.
