The Tayloredge supply is quite well behaved as well as robust, inexpensive, 
small, and already available.

However, Nick, Grahame, and I are toying with the idea of implementing 
something like the supply in that application note.  The core of it (a Royer 
oscillator and matching step-up transformer) is basically an ordinary CCFL 
supply, so I built my initial versions around surplus CCFL supplies I picked up 
on the cheap.

The tricky part is the transformer, and the ones mentioned in the app note 
don't appear to be off-the-shelf parts, but a few phone calls to Coiltronics, 
Coilcraft, or Pico might yield information.  Grahame and I have also worked 
with Custom Coils before for custom transformers, they're good to work with for 
hobbyist quantities.

Thanks! I'll see if maybe they have a reasonably priced demo board. I 
suspect perfect layout is needed to achieve the low noise figures and 
that is beyond me.

Hi,
I'm also looking for this for the same reasons.
Unfortunately I don't have the knowledge to design the board on my own.
Does anyone have something he is willing to share or sell, such as eagle files 
or a finished board or anything in between?
Or is there a finished product or product line out there that would work in 
this situation?

Thanks for your help.

This was always going to be a good design - did you note who wrote the AN?

The late, great, Jim Williams.

Hi All,

Finally working on my fantasy radio, with nixies for frequency display 
of course! And IN-9 or 13 for the S meter, eye tubes for forward and 
reflected power and so on.


What I need is a super quiet DC to DC power supply for the display. I 
can stuff it in a separate box if need be but would like to put it in 
the same enclosure as the transceiver. Any recommendations?
