A Kapanadze generator replication - Febuary 2013

Hi zcsaba77.

My own theory for the top transformer is that it further boosts the voltage from the output coil and as a byproduct, improves the output waveform to a decent sinewave. Eary tests on my coil and ferrite setup (without bias coils) Secondary winding of 30 turns 2 layers, lit a 40 W incandescent lamp to about 1/4 bright.
Looking back I should have tried a transformer. The major problem is that you can't apply test equipment to the circuit because of the HF that's flying about!!

It is still early evening, I shall see if a transformer does anything.

... you have about this transformer picture?

@grumage:

What you have is at best an incomplete schematics, a design in progress, there are several key parts missing, such as base resistors and supply caps.  Besides, this thread is about builds based on the schematics in the header post, and was started specifically for these, to limit clutter and provide documentation for these.  Not that your questions do not deserve an answer, but I'd like, for the sake of clarity to keep side talk here to the minimum. The forum format is already fairly confusing for documentation. 

Also, as zcaba77 pointed out, it is difficult to discuss a rough schematics like the one you presented here without knowing a bit more about its origin.  There are many schematics that look just like that, that were posted onto forums to illustrate suppositions as to what exactly was shown in replication videos, or to illustrate theories of operation.  I suggest you review thoroughly the schematics before powering up and check for conditions that could blow transistors, and add DC supplies caps, as the circuit will not perform well without them.

Hi guys is this setup good for a monitor flyback instead of an MOT?
Thanks

Hi Tika
great start on this topic
In the energy amplification thread, and  most recently added yt video of a french guy on kapanadze that took him 10 years to have a working one....maybe  as a suggestion to pick up some pointers on the coils   ...
Hope you can give some construction details like the copper pipes   coil set up circuit    ....would love to have that kapanadze  ......
with your expertise as a plus factor.....   and a mindset on miminum budget   ....  ill go for it....also....    thanks    totoalas

Thanks, while shopping, you will realize that the most expensive items are the ferrite cores.  So take your time while shopping and make sure before buying that the ferrite material has a high magnetic permeability, the µ factor.  Second on the list are the high voltage diodes and caps.  Also look for deals on electrical wire and tape, you will need quite a bit of these, depending on the coil you decide to build.

There is on ebay alone a factor of 10 between prices for the same part!  And if it takes 2 weeks or more to get a part from China, then that's the time it takes...  Also power transistors and heat sinks can be salvaged from old equipment.  To be successful in keeping under budget, you have to really be careful and spend a great deal of time looking for the best deals.

Hi Tika  thanks for the tips... as Im in China  so parts abound here   .... I have 20 pcs of crt yokes I used in my ss ssg... and mostly copper and cables are cheap.....
if you can give directions on the parts, size dimensions  we start one step at a time......collecting them
we ll be monitoring your development......
thanks   totoalas
