I haven't tried it yet, but using a tesla coil calculator app (JavaTC), a wire length of
37.5m should work out to about approx. 120 turns on a 50mm OD coil form, and should have
a resonance at around 2.827 MHz. That should be a winding length of about 20cm.
This is calculated using 18AWG magnet wire (0.82mm^2). This allows for a little spacing
between each wire to take into account the magnet wire varnish insulation. This is also assuming
I didn't make an error when using JavaTC.

Since tesla coils (as any coil) can have more than one resonance point, I am not sure if a kacher
driver would operate at that resonance point or another resonance point. I hope to find time to try
this, this coming weekend.

You can probably get it to resonate at a bit higher frequency if you use some spacing between
each winding. Once you add the top loading 'antenna' coil, this resonant frequency will likely
drop, so you may well need to start removing some windings from the secondary from there to tune.
All the best...

Thanks Void. I will shortly be at this point myself, so should be able to report my findings. I think the spacing will be important.

Hi Hoppy.  The calculated numbers I got from that program javaTC seem a little strange to me,
so I will wind my tesla coil secondary within the next little while to see what is up. I am going to use
40m of 18AWG as a starting point and see where that gets me. Seems like the coil winding length should
be longer than 20cm for 37.5m of wire. I'll see how it works out and report back.
All the best...

The diodes and choke in the green box makes the now dc voltage across the bulb go negative compared to ground,  right?
At least it does with me, so ground becomes the more (60V dc in my case) positive side.

Hi Hoppy. It looks looks those numbers I got from javaTC were off.
I wound 40m of 18AWG magnet wire on a 50mm OD pipe (tight wound)
and the winding length came out to about 28cm. If that number was off then
the calculated resonant frequency for 37.5m may well be off as well. Probably have
to reduce the number of turns a fair bit, but we'll see.
Once I test with a kacher driver I will post back the resonant frequency, but I
will probably shorten to 37.5m wire length first to see what the kacher operating frequency
is for that length.
All the best...

Hi Void,

Thanks for your preliminary report.

I've just finished testing my first Kacher secondary wind. I have 26m wound on 50mm pipe for a length of 170mm. Natural resonance using a six turn primary is coming out at 1.6Mhz, injected from SG. My wire is 0.9mm diameter and adjacent turns are not tightly closed-up. I have tried to space the windings slightly.
