Magnetic Resonance Devices based on Don Smith Concepts

[gyulasun]

Mr. Smith says that you can get all the components in any shop, but he says that there are 2 that you cannot get everywhere.
The first ones are the capacitors used just after the NST. I've localized them.
The second ones are 4 high voltage diodes that are just after the L2 coil. Anyone knows any number indentification of those caps or where to get one like them?
Smith also used 2 high voltage diodes just with the yellow caps, that seem to be the same model as the mentioned above. I'm not sure about if the 6 are the same kind of diodes, but in the video he only says that the 4 mentioned are are the difference. Any information about all this?

hi Magnetos,

Here are two links on high voltage and diode / diode bridge and capacitor source:

a manufacturer:
http://www.deantechnology.com/pg_home/home.aspx

a distributor, selection is made on high voltage capacitors in descending order, starting from 16,000V, copy and paste the link below fully into your browser because the last part of the link below is truncated:
http://www.alliedelec.com/search/searchresults.aspx?dsNav=Ny:False,Ns:Voltage%2c+Rating|101|-1|,N:107-4294887054 

Surely there are other sources too, I did a small random search. 

The capacitor shown in the photo you uploded in the previous page:  .1uF  +/-10% 4000WVDC was manufactured in the 2nd week of 1977... this is what the last line shows: 7702

I don't know if they've something special. The yellow caps are 4000 WVDC 0.1 uF each one (there are 2). I think they're made of mica (not sure).
About the high voltage diodes I've no information. But he says that you cannot buy them everywhere. Well, the video is from the 1990's, so maybe in that time you cannot buy them everywhere but now... who knows.
I don't know why he says that you cannot buy them everywhere. The caps are made by a company that build electronic components for the military (and other) industry.
This cap is rated the same as Don Smith's ones. http://www.apexelectronic.com/FC2-W-4A
but I don't know if they Smith's ones has some advantage or not.

What means WVDC? I'm used to see 4000 Volts DC but... WVDC? You know if the caps are special made?

update

Yes, the caps are of mica.

WVDC means Working DC Voltage,   see the very bottom of this link for explanation:
http://www.illinoiscapacitor.com/tech-center/glossary.aspx

I do not think these capacitors are special made.  Here is one of the better capacitor manufacturers, the Cornell Dubilier,  CDE for short,  This is their website:  http://www.cde.com/   with some  high voltage products: http://www.cde.com/catalog/hvolt/ 

They have a CMR series product (the first line on the yellow cap starts with CMR), see this:
http://www.cde.com/catalogs/CMR.pdf    You may get in contact with them whether they manufactured CMR 1A 402104K type back in 1977 and what they recommend nowadays....   but again, I do not think this cap is a special made one.

Don Smith had caps made at one of these vendors:

1. Custom Electronics - http://www.customelec.com/
2. Cornell Dubilier      - http://www.cde.com/

Good luck

I think this is last lecture of Don Smith Device concept.
